Question: His parents, Chris Gard and Connie Yates, have launched a final legal challenge at the European court after their Supreme Court challenge failed. They want the 10-month old to undergo a trial in the US, but London specialists believe he has no chance of survival. The European court wants until Tuesday to consider the case. Judges in Strasbourg, France, ruled that Charlie should receive treatment while they look at paperwork in the case. The court said this type of interim measure was exceptional, when the applicants would face a "real risk of irreversible harm". A spokeswoman said Charlie's parents wanted a panel of seven judges to look at the case in detail. No decisions about whether or not the case would be analysed at a hearing had yet been made, she said. Charlie has been in intensive care at Great Ormond Street Hospital since October last year. He has mitochondrial depletion syndrome, a rare disorder that affects the genetic building blocks that give energy to cells. Doctors say he cannot hear, move, cry or swallow and that his lungs only go up and down because he is on a machine that does it for him. Specialists believe the US trial is experimental and will not improve his quality of life, and therefore he should be allowed to die with dignity. Charlie's parents have exhausted all legal options in the UK. 'Not a cure' On Tuesday, the High Court ruled that life-sustaining treatment could be withdrawn, and on Thursday, the Supreme Court rejected the parents' appeal against that decision. The Supreme Court said parents were not entitled to insist on treatment which was not in their child's best interests. Charlie is thought to be just one of 16 children in the world to suffer from mitochondrial depletion syndrome. His parents have managed to raise £1.3m on a crowdfunding site to pay for the US treatment and to get him to the country safely, as a specialist plane and nurses are needed. The American doctor who has agreed to treat Charlie has previously told the High Court the six-month therapy would be "treatment but not a cure". The neurologist who would oversee the treatment told the court that while Charlie was in the "terminal stage" of his illness, treating him would be compassionate. He added that there could be a meaningful improvement to his brain function meaning that he might be able to interact and smile.

Answer: Terminally-ill baby Charlie Gard must continue to receive life-support treatment until Tuesday, the European Court of Human Rights has said.


Question: The announcement came after eurozone ministers approved a Greek request for a two-month extension to its bailout programme, due to end later this month. The presidential vote on 17 December will be a vital test for embattled Prime Minister Antonis Samaras. His decision prompted the stock market in Athens to plummet 9.5% on Tuesday. Analysts said the markets had been spooked by the risk of snap elections, which will take place if the conservative-led government's nomination is not approved by parliament. President Karolos Papoulias's five-year term ends in March, and a vote had been expected in February. Mr Samaras's conservative-led coalition needs the support of other parties if its candidate is to obtain the backing of MPs. But the left-wing anti-bailout Syriza party is leading in the opinion polls and the government faces widespread public discontent after a six-year recession. Risky vote Hours after saying he would bring forward the presidential vote, Mr Samaras gave a televised address announcing that his coalition was nominating former European Commissioner Stavros Dimas as its candidate. "When the current parliament elects a president at the end of the month the clouds will be gone and the country will be ready to officially enter the post-bailout era," the prime minister said, linking the vote in parliament to the end of the unpopular programme of support from the EU and IMF. Since 2010 Greece has received almost €240bn (£190bn; $295bn) in rescue funds, which are due to be replaced next year by a new eurozone credit line that can be accessed in an emergency. Syriza's leader Alexis Tsipras accused the government of rushing it through in a "desperate attempt" to hide new austerity measures. He has pledged to end austerity cuts and any co-operation with either EU or IMF lenders. Mr Samaras's government narrowly pushed through its 2015 budget in the early hours of Monday, securing 155 votes in the 300-seat parliament. But if it is to convince MPs to back its presidential candidate it will need far greater support from the chamber. Two hundred MPs are needed to back a candidate in the first or second vote, and 180 for the third vote. The second and third rounds of the vote are scheduled for 23 and 29 December. Mr Samaras will have to secure the backing of 25 opposition lawmakers to reach 180 votes. Monday's move to extend the bailout and advance the date of the presidential vote came a day after violent protests in Athens, with more than 300 demonstrators arrested. The demonstration was held to mark six years since police shot dead an unarmed teenager during protests fuelled by anger over the country's economic crisis. "The coming period is essential to find an agreement [with the eurozone] to settle issues like the debt, and Greece has to have the full capacity to mobilise its forces in a climate of national unity and political stability," the government said in its statement. Some investors are worried about a return to the days of financial crisis as the presidential vote looms.

Answer: Greece has brought forward to this month the date of its next presidential election, which is conducted by the country's parliament.


Question: Speaking to the BBC's Newsnight, Sir Elton said companies "haven't done anything to try to stem the flow of hate on the internet". His interview followed him giving the Diana, Princess of Wales lecture on HIV, in which he called on firms to harness their social power. He said a boycott could make the firms "sit up" and take action. Sir Elton said to Newsnight's Kirsty Wark: "I don't know why they [social media firms] allow it - it's supposed to be free speech but the things that are on social media are so disgusting that there has to be action taken by the people who own these companies." He added: "'People say 'well what about my freedom of speech?' Well, sod your freedom of speech." He then called for a boycott, saying: "Why not? Then they'll sit up. When the money is not coming in they'll sit up. "They can do so much good, but first they have to clean house and become a much more moral and Christian thinking... a moral thinking compass for what's going on in the world. "At the moment they're not doing that." Earlier, in his lecture, Sir Elton told an audience of politicians, health workers and celebrities in London: "Companies like Facebook and Instagram cannot pretend they are purely private enterprises. I believe they have a public role and responsibility. "Imagine if they put their mic behind debates that could counter ignorance. Homophobia fuels shame, isolation, cruelty and anger, and therefore HIV. "But if we found ways to automatically respond to hatred with fact, good could be all the way around the world before falsehood even got its boots on." Sir Elton praised the work of his close friend Diana, Princes of Wales, in championing Aids and HIV treatment. In a famous moment from the 1980s, when many still thought the disease could be contracted through casual contact, Diana sat on the bed of a man with Aids and held his hand. The National Aids Trust began the lectures in 1999 as an honour to the late Princess.

Answer:
Sir Elton John has called for a boycott of social media giants to force them to tackle homophobic hate speech.
