ISIS Claims Top Spokesman Killed in Syria
QUEST: More on that unprecedented announcement. ISIS says one of its top spokesman has been killed in Syria. Nick Paton Walsh is in southern Turkey. Nick, apologies we weren't able to get to you a second or two ago when we tried. I just really need to know why do you think they've taken this unprecedented step in announcing this death?</s>NICK PATON WALSH, CNN SENIOR INTERNATIONAL CORRESPONDENT: I don't see what they have to gain at this stage. One potential explanation is that in fact, they're faking his death to buy him cover to move around more cautiously. We have in fact just heard from a spokesman in the pentagon suggesting that in fact an ISIS senior leader was targeted by an air strike in a town called Al-Bab, which fits geographically the place where ISIS accept. In these two statements, that Mr. Adnani was in fact killed. That's in the area of Aleppo. It is also quite likely that they wanted to get perhaps ahead of the message here to some degree. They have nothing to gain in announcing the death of such a high profile figure. This is a man who spearheaded attacks against the west, who came up with the formula, that is so redolent in ISIS attacks in European capitals. You don't really have to get direct instructions from us, the ISIS main body. You can go off and do what you wish and subsequently we may take credit for that. That's become a warped model of the lone wolf terrorist idea that's caught on. Certainly you seen in the last summer here. So they are in a very bad... I'm not at all sure what happened there. But we clearly lost Nick Paton Walsh. And we got an early view of Mohamed El-Erian, which is also nice to see. And all follows the day after France's trade minister told CNN that the situation with the Transatlantic trade deal was unacceptable. France now says talks should be stopped. He plans to ask for a halt at next month's EU meeting in Bratislava. Mohammed is with me. He's the chief economic advisor at Allianz. Mohammed, good to see you. Let's check, first of all that we can see you and that you can hear me. Are you there, sir? It's turning into one of those days. When things go wrong, they go wrong on a giant scale. The Chinese state media says next week's G20 summit will be a vital opportunity to get trade talks going again. The Brexit vote has made the picture far more complicated. Now, with a bit of luck and the following wind, and assuming things are working as they should be, and we've paid the electricity bill, Isa Soares has a report.</s>QUEST: The British people have voted to leave the European Union.</s>UNIDENTIFIED CORRESPONDENT: It was a decision that made headlines right around the world.</s>CHRISTIANE AMANPOUR, CNN ANCHOR: The sun has risen on a completely different U.K. and a completely different</s>EU.

But fast forward two months. And with world leader preparing to meet the G20 summit in China, does Brexit still matter?</s>ALAN WHEATLEY, ASSOCIATE FELLOW, CHATHAM HOUSE: I do think this is an issue that is going to detain the G20, as long as Brexit, and this is an important caveat, as long as Brexit doesn't lead to a big recession in the U.K. that then spills over into Europe and into the rest of the world economy.</s>SOARES: On her first day as the U.K.'s new prime minister, Theresa May sought to put mind at ease that Britain is still relevant, both at home as well as abroad.</s>THERESA MAY, BRITISH PRIME MINISTER: Following the referendum, we face a time of great national change. And I know, because we're Great Britain, that we will rise to the challenge. As we leave the European Union, we will forge a bold, new, positive role for ourselves in the world.</s>SOARES (on camera): A bold pledge made right here a few weeks ago and one that may face some difficulties in the months ahead. Sure, Britain is still one of the world's leading economies and a major player when it comes to its military. The challenge for the new prime minister, Theresa May, is whether she can convince other countries of a vision of Britain on the international stage. One man who knows how to navigate the world of diplomacy is Rupert Harrison.</s>RUPERT HARRISON, CHIEF MACRO-STRATEGIST, BLACKROCK: A lot of what's really being decided is not actually happening in the room.</s>SOARES (voice-over): He attended many G20 summits with former chancellor George Osborne.</s>HARRISON: Our main goal at this G20 is to get to know her counterparts, establish those relationships, and then also to send a message about the U.K. I think an important message she needs to send and will want to send is that the U.K. is still open for business. We want to be a global trading nation, that leaving the European Union doesn't mean we're going to pull up the drawbridge or that we don't want to be key players in the global economy anymore.</s>SOARES: That may well be the strategy going into this summit. But with the process of exiting the European Union taking at least two years, Britain will fight hard not to burn any bridges.
