[EX Q]: The deal - one of the biggest this year - still needs approval from regulators. If the takeover goes through, it would combine AT&T's distribution network with content from the Warner Brothers film studios and the cable TV channels HBO and CNN. AT&T's chairman described it as "a perfect match" but critics say it concentrates too much media power. 'Complementary strengths' The deal is likely to be closely scrutinised by US antitrust regulators. AT&T is already the third largest cable TV provider in the US. Randall Stephenson, who is both chairman and chief executive of AT&T, said he did not anticipate any regulatory obstacles, saying any concerns could be overcome if concessions were made. "This is a perfect match of two companies with complementary strengths who can bring a fresh approach to how the media and communications industry works for customers, content creators, distributors and advertisers," he said. Analysis: Joe Lynam, BBC correspondent AT&T has the means by which millions of Americans consume their entertainment. It owns the platform - be that cable or broadband - which enables people to watch their favourite shows. But it does not - until now- own the shows or the "content" which households want to watch, be that Game of Thrones, CNN or live NBA basketball. Buying Time Warner, which we should not confuse with Time Warner Cable, allows AT&T to become a full service media provider and one of the more important companies in the world. It allows a newly-merged entity to steal a march on the likes of Verizon or Comcast in a very competitive US market. But the deal may never happen. It could be deemed anti-competitive by regulators because AT&T already owns mobile phone, broadband and cable TV networks, and allowing it to control the shows as well might deprive consumers of choice. An AT&T statement said that aim of the deal was to give customers "unmatched choice, quality, value and experiences that will define the future of media and communications" and the new company would "lead the next wave of innovation in converging media and communications industry". Republican presidential candidate Donald Trump has said if he is elected, he will block the deal. "It's too much concentration of power in the hands of too few," he said on Saturday, before the deal was confirmed. AT&T will pay $107.50 for each Time Warner share, in a combination of cash and stock, worth $85.4bn overall, according to a statement. AT&T said it expected the deal to be completed by the end of 2017. Other media company shares, including Discovery, AMC, Netflix and CBS, recently rose as investors speculated that a deal could spark a fresh wave of takeovers and mergers among media and technology companies. AT&T, which has a market value of about $238bn, has already made moves to turn itself into a media powerhouse, buying satellite TV provider DirecTV last year for $48.5bn. Time Warner chief executive Jeff Bewkes has, however, resisted selling in the past. The company rejected an $80bn offer from Twenty-First Century Fox Inc in 2014. The deal gives AT&T access to a major producer of content as it seeks to diversify away from its core telecoms business. Rival Verizon is currently in negotiations to buy Yahoo and has already bought AOL, owner of Huffington Post. Some analysts, however, question whether AT&T needs to mount a complete takeover of Time Warner.

[EX Q]: Brodie Clark was suspended by the Home Secretary Theresa May last week after being accused of relaxing immigration controls beyond what she had asked for. He now plans to lodge a claim for "constructive dismissal", and has denied acting improperly. Earlier, Mrs May said he must "take full responsibility for his actions". The home secretary allowed some checks on European travellers to be relaxed, but says Mr Clark went further in scaling back checks, without her approval. Three-hour queues In a statement, Mr Clark said his position at the UK Borders Agency had been made "untenable" because of the statements made in the House of Commons by Mrs May. "Those statements are wrong and were made without the benefit of hearing my response to formal allegations," he said. "The home secretary suggests that I added additional measures, improperly, to the trial of our risk-based controls. I did not. Those measures have been in place since 2008/09. "The home secretary also implies that I relaxed the controls in favour of queue management. I did not. "Despite pressure to reduce queues, including from ministers, I can never be accused of compromising security for convenience. "This summer saw queues of over three hours (non EU) on a regular basis at Heathrow and I never once contemplated cutting our essential controls to ease the flow." He said he was saddened his career should end in this way after 40 years of "dedicated service", and regretted Mrs May had "disregarded my right to reply" in favour of political convenience. Although Mr Clark has left the Civil Service, technically he has not resigned, said Jonathan Baume from the First Division Association, the trade union which represents senior civil servants He said Mr Clark had been willing to answer the issues raised internally. "But instead he was suspended and the home secretary has spent two days basically traducing him and damning him without ever giving the civil servant the opportunity to present their case." Mr Clark - one of three UKBA officials suspended last week - is due to give evidence to the home affairs select committee next week. Full responsibility Earlier, Mrs May faced questions from that committee about her involvement in a pilot scheme. She told MPs she had not told the Cabinet of her decision to allow officials to relax checks on some European travellers arriving in the UK as the "limited" pilot was an "operational matter" which "did not in any way put border security at risk". She said the idea was that at busy times it was safer to carry out "intelligence-led" checks on suspicious passengers rather than mandatory checks on all passengers, including those who were "low risk". Labour committee member David Winnick suggested ministers should take full responsibility for a "major blunder" on their watch and asked if there was any question of Mrs May resigning - to which the home secretary responded: "No." She added that she would take responsibility for the authorised pilot, which she suggested had led to a 10% rise in the detection of illegal immigrants, but Mr Clark must "take full responsibility for his actions". Mrs May has announced there will be three inquiries, the main one led by the Chief Inspector of the UK Border Agency, John Vine. Shadow home secretary Yvette Cooper said the "fiasco" for the home secretary was getting worse, now her version of events has been contradicted by "her most senior official" at the UK Border Force. "First she decided to reduce border checks then lost control of her so-called 'pilot'. Now she has lost the loyalty of one of her most senior civil servants. The home secretary clearly doesn't know what has been happening at our borders." 'Completely contradictory' Labour has put forward an opposition day motion calling for the government to publish the instructions Mrs May and Immigration Minister Damian Green gave to UKBA during Wednesday's debate on the affair. The motion also asks whether they signed off operational instructions giving UKBA greater flexibility. Labour MP Keith Vaz, the chairman of the home affairs committee, said Mr Clark "cast very serious doubt" on the home secretary's account his committee had heard just hours earlier. "It's completely contradictory to what she said. This is a complete turnaround of events." Speaking on BBC's Newsnight programme Mr Vaz said the committee would be writing to Mrs May with a number of new questions. Chief executive of the UK Borders Agency Rob Whiteman said he suspended Mr Clark after he admitted last week to authorising staff to go further than ministerial instruction, on a number of occasions. "In my opinion it was right for officials to have recommended the pilot so that we focus attention on higher risks to our border, but it is unacceptable that one of my senior officials went further than was approved," he added.

[EX Q]: Earlier this week, the story about Merida, a headstrong Highland princess, was nominated for a Bafta. It features the voices of Kelly Macdonald and Billy Connolly. The film's score includes songs performed by Gaelic singer Julie Fowlis. Pixar writers and artists visited the Highlands, Argyll and the Western Isles to research Brave's story and animation. The Pirates! An Adventure with Scientists, which Bristol-based Aardman Animations helped to create, Wreck It Ralph, Frankenweenie and Paranorman have also been nominated for the same Oscar. Scotland's first minister, Alex Salmond, welcomed Brave's Oscar nomination. Tourist body VisitScotland created a multi-million pound tourism campaign to tie in with the release of the film last year. Mr Salmond said: "This nomination is fitting recognition for Brave, and caps a great year for a great film - coming on the back of yesterday's Bafta nomination for best animation. "Brave has been a terrific showcase for Scotland and has given this country the unprecedented opportunity to be promoted across the world, being marketed in some 72 countries."
