CUOMO: All right. Just two days until the British people have to decide if they want to remain in the European Union or break away. Now, this decision is going to have big affects across the globe. So, let's bring in CNN international correspondent, Phil Black, live in London with the latest. What is the state of play, my friend?</s>PHIL BLACK, CNN INTERNATIONAL CORRESPONDENT: Chris, it is still so very close. The polls are still so tight, it is really too close to call. As you say, just two days of campaigning left. So in that context, tonight's final television debate is potentially quite crucial. It's going to be before an audience of 6,000 people at Wembley Arena in London, it could get a little rowdy, and both sides are going to be looking to a clear result, score some clear points. What we've been seeing in the final days are both sides doubling down on their key messages. For those who want to stay with the E.U., led by the Prime Minister David Cameron, they are talking about this being a lifelong decision, one with potentially disastrous consequences for the British economy. Those in favor of Britain leaving the E.U., the Brexit camp, they say this is all about controlling immigration, returning sovereignty to Britain. You really can't overestimate the strength of political feeling in this country at the moment, especially after that tragedy last week. The shooting death of the MP Jo Cox, who favors sticking with the E.U., knifed and shot by a man who was said to be calling out, "This is for Britain." It's a highly emotional time, because so much is at stake. It's not just a general election. It's about the direction of the country for decades to come. Brooke, back to you.</s>BALDWIN: All right. Phil, we'll watch it on Thursday. Thank you very much in London. Coming up next here, a new concern about lone wolf attacks in the wake of the Orlando shooting. Similar concerns around the world, as well. We'll preview tonight's CNN special report on the Paris terror attacks, next.
