英国新闻听力 前伦敦市长鲍里斯·约翰逊决定退选（在线收听）

The contest to become the leader of Britain's governing Conservative Party and Prime Minister has taken a dramatic twist, with the man widely-tipped for the post Boris Johnson pulling out of the race. The decision of Mr. Johnson, the most prominent figure in Britain's campaign to leave the European Union, shocked the political establishment, as our political editor Laura Kuenssberg reports. The biggest name bows out. Whether it's treachery or tragedy, Boris Johnson, known universally for his desire to become Prime Minister, has quit the race, and not even a week since the referendum results. It has unleashed a day of bitterness and recrimination inside the Conservative Party. There are several accounts of exactly what happened. Suggestions that Mr.Gove has been plotting for months, fiercely denied. Allegations that Boris Johnson was not getting enough support from MPs, that's Gove act too. But the only certainty, perhaps, is that a group of senior Tories who, for years, have seen themselves as in charge of the party's destiny, are at total odds with each other.

The reduction has been credited to the long-term phasing out ozone-destroying chemicals, which were widely used in refrigerators, sprays and air-conditioning.

A judge in the United States has ordered the retrial of a convicted murdered, whose case featured in Serial a hugely-popular podcast, which cast out on the evidence presented at the original trial. From Los Angeles Peter Bowers. Adnan Syed has been serving a life sentence since being convicted 16 years ago of killing Hae Min Lee, who was a former classmate. At a court hearing earlier this year, Syed's lawyers argued that a crucial alibi witness and questionable mobile phone records were wrongly overlooked by his original defence lawyer. Now, a judge has said the lawyer rendered ineffective assistance, when she failed to cross-examine the prosecution expert about the evidence. The judge said he'd been swayed by new evidence uncovered by a spin-off podcast called Undisclosed, which followed up the story, after Serial became the most popular podcast of all time.

After music and readings written by those who saw the battle firsthand, soldiers from nations that once fought here began a rotating guard that will continue throughout the night.
