union, this is their last great hope to have a second referendum and essentially it's boris johnson's deal or we remain in the european union. >> you laid out three -- >> everything he can to fight against that. >> okay. you laid out three options. i will ask you to play handicapper, between options parliament passes the deal, brexit happens without a deal, this confirmatory referendum, which is the most likely thing that ends up happening here? what do you think based on your analysis and reporting on this issue? >> so i think that just doing the math at the moment, i think there are most numbers to get a confirmatory referendum. the leader of britain's labor party, the main opposition group has said yes, we support the referendum. that's happened today. an awful lot of people who are likely to back that. so i think that it's perfectly possible that britain could be thrown into another referendum. i think there will be legal challenges about whether that's possible, but i think it is entirely conceivable, hallie,
