It emerged last month that checks had been put on hold so officials could deal with queues at passport control. Critics say efforts to tackle illegal immigration were effectively neglected. But Border Force boss Sir Charles Montgomery told MPs a queue of vehicles was itself a security threat as it was vulnerable to "clandestine" migrants. According to a National Audit Office report published last month, officers were ordered on three successive days to switch from searching for contraband and illegal stowaways to checking passports to prevent big queues building up at Calais and other entry points, ahead of last year's Olympic games. 'Clear rationale' Freight searches were also suspended due to understaffing and to allow staff to have meal breaks, although vehicles continued to be searched by French officials and sniffer dogs used by the Border Force. Sir Charles, a former senior Royal Navy officer who became Border Force boss in March, told the Public Accounts Committee that checks had not been totally abandoned. But he said it was "absolutely right" to shift the resources at the Border Force's disposal where necessary to prioritise "traffic flows" at points of entry. "There is a very clear rationale for this and it is driven by the primary objective of the Border Force which is national security. The flows of traffic approaching Calais are themselves important for security. "The checks and controls can create backlogs of stationary traffic of up to three miles if not properly managed. "Those queues are a primary source of security concern because stationary traffic - particularly soft-sided traffic - are a primary target for the clandestines trying to get through the border." Labour MP Margaret Hodge, who chairs the cross-party committee, questioned why the decision had only come to light in the watchdog's report and why officials had not disclosed what was happening earlier. The Border Force did "not want to put into the public domain the possibility or probability at any given time of checks having been suspended", Sir Charles said. But Mrs Hodge replied: "If I may say so, it is not putting it in the public domain which is wrong, it is the action of suspending it which is wrong... it is the action, not the reporting of the action, which is vital." Manpower The National Audit Office has suggested a lack of manpower was to blame for resources having to be juggled. The number of full-time border staff fell from 8,023 to 7,527 between April 2010 and March 2012. But since separating from the Border Agency, the agency's budget has increased and funding is in place to increase staff numbers to 8,477 by next year. The Border Force was brought under the direct control of the Home Office in 2011, when the UK Border Agency was abolished following a row over the relaxation of passport checks at Heathrow without the authorisation of ministers. Sir Charles told MPs that coach parties of schoolchildren had been subject to less formal checks at Calais this summer under a pilot scheme to reduce delays, the results of which were now being evaluated. The children had not been required to disembark and face-to-face checks had been carried out on the vehicle, he said. He stressed the initiative had been pre-authorised by the Home Office and followed a risk-based analysis.
The UK's most senior immigration official has defended the suspension of customs checks on vehicles at Calais as necessary to protect national security.

Rapman said Blue Story had nothing to do with a mass brawl involving machetes at a Vue in Birmingham, which left seven police officers injured. Vue pulled the British film, saying it had sparked 25 incidents nationwide. But Rapman said there "was no link to Blue Story" and asked whether there were "hidden reasons" behind the ban. Five teenagers were arrested after the fight in Birmingham's Star City complex on Saturday. The writer and director told BBC arts editor Will Gompertz: "They were just in a cinema apparently for Frozen [2], but then they pinned it on Blue Story." Vue said there had been a total of 25 "significant incidents" at its sites around the country, all involving people either watching, buying tickets for, going in to watch or leaving screenings of Blue Story. Rapman, real name Andrew Onwubolu, said there was "no connection" between the Birmingham brawl and his movie. "And then you start thinking, is there hidden reasons there? What's the owner like? Has he got an issue with young urban youth? Is he prejudiced? Does he believe that this film brings a certain type? Is there a colour thing? "You start thinking of all these things, and it was an upsetting time." A spokesperson for Vue said the decision to pull Blue Story from its 91 cinemas nationwide was "categorically not" related to race. The rapper-turned-film-maker, who rose to prominence in 2017 with his hit YouTube series Shiro's Story, said taking a machete to a cinema was "barbaric", but asked Vue to give details of the other incidents. Speaking on BBC Breakfast, he said: "They say that there's been a number of incidents, but where's the proof? Where's the evidence? Where? "We live in a camera generation now. If anything happens, the youth are going to film that and you will see it. How come we haven't seen any footage of the rest of these incidents? "I feel like that was just something to say to cover their decision, which already wasn't justified because the [original] incident had no connection to Blue Story." What have Vue said? Vue founder and chief executive Tim Richards said incidents involving groups took place at 16 cinemas in total, starting on Friday morning - the day of Blue Story's release - until Saturday evening, when it was pulled. "In over 30 years of working in cinema exhibition in the UK, I have never seen a nationwide issue like this affecting so many cinemas in such a short space of time," Mr Richards said. The chain classes "significant incidents" as those involving illegal activity, harassment, intimidation, violence, public disorder, or anything requiring security, medical, fire or police intervention. But Vue has not given specific details of the incidents or where they took place. "We have reviewed and assessed each and every incident in detail as part of our ongoing process of making decisions as to how we could possibly keep Blue Story on our screens," Mr Richards said. Additional security was put in place, but "we were still not satisfied the risk had been reduced to an acceptable level", he added. Mr Richards also said Blue Story, which has a 15 certificate, attracted a "very young audience". Reports suggesting those involved in the incidents were there to watch other films - such as Frozen 2 - were "simply not true", he added. "A younger audience were attempting to purchase tickets for other movies to access the Blue Story screenings and were also resisting requests for ID. This also played a key role in incidents and our decision." 'Lucky there were no serious injuries' West Midlands Police and Crime Commissioner David Jamieson told BBC Radio 4's Today programme that "officers were attacked by quite young children" in Birmingham on Saturday, including "12, 13-year-olds who were there in quite large numbers". His force had not asked the chain to pull screenings of the film, he added. "But we have to ask why and how did so many young children turn up in such quite large numbers, some of them armed to attack other people. It's fortunate there wasn't any serious injury on Saturday, but my goodness there could have been." Film company 'offered extra security' Rapman said he knew his film would appeal to young people, but he had no reason to suspect it might attract violence. "The two gangs that the film's based on, which are real gangs, have been in a cinema screen watching it together, laughing together, joking together, and leaving a cinema connected, happy seeing the area they grew up in." Blue Story follows the life of Timmy who lives in Lewisham but goes to school in Peckham - two areas that have a notorious rivalry. It is released by the Paramount film studio, which offered to provide extra security at cinemas, Rapman said. The movie is also backed by BBC Films. "Paramount have definitely offered every single site extra security if they need it. How hard would that be to just get more [security] people there?" 'They bullied me' Showcase originally followed Vue's lead in pulling the film, but later reinstated it. Odeon and Cineworld have continued showing the movie. Vue's move has led to a vocal backlash, with some accusing the chain of being "institutionally racist". Vue has said its decision was made "on grounds of safety alone" and not because of "biased assumptions or concern about the content of the film itself". But Rapman said: "They've alienated themselves from a big audience there. The explanation came with no evidence, no facts. "I feel like they bullied me because I'm a small film. They wouldn't have pulled Frozen, they wouldn't have pulled Last Christmas. They pulled a little independent movie that needs it more than them other movies." He feels "cheated" as a result, he added. "I feel it's always the upward hurdles coming from our background. I always knew it was never going to be smooth. But the last thing I thought was a cinema would ban us from every single site. I just don't think they respect me. They don't respect my movie." Film is 'about love, not violence' Rapman said Blue Story is "about what people do for the people they love, and how love can make people make the wrong decisions - and the right decisions sometimes". He told BBC News: "If you watch the film, you will understand. The last line of the whole trailer is, 'I'm not trying to justify, but I'm going to show you what these young boys are fighting for'. "I'm not justifying their actions, but go and see why they are fighting, see why they're stabbing and see what they're doing all these things, just so you can see their motivation and maybe we can help prevent that, so they don't have to pick up a weapon again." In his statement, Vue's Tim Richards added: "We wholeheartedly agree that the issues that have arisen are not about the film, but neither are they about Vue. The chain screens more than 500 films a year "in a range of diverse content", he explained. "We are in the business of showing movies, not withdrawing movies." Blue Story opened on Friday 22 November on 310 screens in the UK and Ireland and made £1.3 million over the weekend. That was enough to secure it third place on this week's UK and Ireland box office chart, behind Frozen 2 and Last Christmas. Follow us on Facebook, or on Twitter @BBCNewsEnts.

The director of a film at the centre of a storm over violence in cinemas has said he feels "bullied" and "cheated" after it was banned by the Vue chain.

By Jane DeithFile on 4 It's a gorgeous warm evening in the South West of England and Sarah - not her real name - has a date. She's wearing a summery skirt and top. She's strikingly pretty. In her 20s Sarah, who has learning disabilities, left home to have her first taste of independence. She moved into a flat - the council call it supported living - where there was help on hand during the day. It was a big step for her. When a man who lived in another flat and also has learning disabilities asked Sarah out, she was excited. She says she "wanted something happy to happen". "He took me out for meals sometimes. He even wanted to get married to me or I wanted to get married to him," she explains, "he even proposed to me twice in one evening in two different clubs." But Sarah explains that while he was nice to her in public, when they were alone together in his flat he could be unkind, shouting at her and throwing things. Sarah's family became worried that her new boyfriend was controlling her and her mother noticed she had bruises. One of the hardest things for Sarah was navigating their sexual relationship. She says sometimes she felt she had to be intimate with her boyfriend, even when she didn't want to. "We would be going to bed and having this and that and when I would say can you get off please or I don't feel like it, he would say don't you love me, and make me feel guilty," she says. "And then when we were having our session sometimes my head would bang on the wall and my mum saw lots of bruises and when I was having a bath in his flat he would want to take pictures." She says she thought she was in love and feels he played on her emotions, even though he, too, had a learning disability. Sarah didn't want to tell her mother everything that was happening, because she was afraid she would get into trouble. Her boyfriend said her family didn't want her to be happy and, feeling as though she was "in a trance", she ignored her family's warnings. Sarah's mother "Chrissy" asked social services and the police for help, but they said they couldn't really do anything because Sarah was an adult. "All the way through the supported living whenever we had reviews, I'd say, 'she needs help with relationships,'" Chrissy explains. "But the reply was always that's she's an adult and that she's got her own choices to make." Respond is a therapy and advocacy charity for people with learning disabilities who've experienced abuse or trauma. Chief executive Dr Noelle Blackman says the welcome move away from living in institutions or care homes, to independent living, carries risks. "We want people to live normal, ordinary lives, but the way that we do that is actually by providing very little support. You find people with learning disabilities who have difficulty in keeping themselves safe, given two or three hours of support a week," she says. She says that people with learning disabilities are often living in blocks of flats in gang areas. "It's like walking around with a label saying 'I'm a vulnerable person'. We're in danger of being neglectful and not making sure that we're helping people to live safely." Chrissy had to wait for Sarah to cry for help, and one night she did. She asked her parents to take her home but the man she left wrote to her, and she started seeing him again, in secret. She says she didn't know what to do, and was very upset and confused. She even emailed strangers on the internet asking for advice. Then one day she poured her heart out to a taxi driver. The police believe when he realised Sarah was vulnerable, the driver deliberately groomed her. She says took her out for a drink and told her she was lovely, and so pretty he couldn't understand why her boyfriend was treating her badly. He said he would drive Sarah home but he pulled over in a lay-by and sexually assaulted her. The driver was arrested, questioned and then released. He said Sarah had consented to being touched. But Sarah's mother says the police said they didn't believe that. But, without DNA there wasn't enough evidence to charge him. Mencap says people with learning disabilities may be up to four times more likely to suffer sexual abuse. The Crown Prosecution Service doesn't record how many people are prosecuted for sexual offences against people with learning disabilities. But a study by Mencap in 2001 revealed there were around 1,400 cases a year, but only 1% resulted in a conviction. The Crown Prosecution Service says there are special measures available to help vulnerable people give evidence in court, for example speaking behind a screen, or recording it in advance on video. Intermediaries can help a witness who finds communication difficult. Neither of the men who exploited Sarah have been charged. It took a long time for her to recover but now she helps run sessions for people with learning disabilities, spreading the message about the dangers of sexual exploitation, and how to form positive relationships. And Sarah now has someone good in her life. She has a boyfriend who loves her and looks after her. Their date tonight is a special occasion. It's the anniversary of their engagement. You can hear more of Sarah's story in File on 4, tonight at 20:00 BST on Radio 4. Follow @BBCOuch on Twitter and on Facebook, and listen to our monthly talk show

As police chiefs and disability groups warn people with learning disabilities are at risk of being targeted by groomers, "Sarah" tells her story.
