>> 10 PM in London, the cut off to vote on what's being built as this generation's most important referendum. As Britons dry themselves off after a day of torrential rain in some areas, polling stations firmly shut their doors. Behind them, the count begins to decide a final result.
Will Britain leave or remain in the European Union? Reuter's UK Bureau Chief Guy Faulconbridge on what happens next.>> Votes will be counted, and first of all, we're gonna get partial numbers for turnout in all 382 different areas across the country at different times. After that, we're gonna get the ye/no percentages for each of those 382 different areas.
We expect the result early on Friday morning.>> Peak time for anyone suffering from referendum anxiety. Paul suggests it's too close to call, and it may all come down to how many people hit the ballot box. A record 46 million people are registered, but some fear voters may have been deterred after heavy rain flooded some streets, forcing several polling stations to close.
>> Turnout could be key for this referendum. If turnout is below the 66% that turned out in the 2015 general election, then leave could well be winning this referendum. If it's above 66%, according to campaigners on both sides, that remain could be the one that wins the referendum.
So turnout is really crucial.>> Some though, certainly, not put off by a bit of British summer rain. Key faces from each side of the campaign headed in to cast their votes earlier on Thursday. The outcome could make or break political careers. No doubt each will have a bottle of bubbles in the fridge back home and in only a matter of hours, Britain finds out who gets to pop the cock.
For some, though, neither outcome will be a cause for celebration. They may wonder how a country so divided over this question could ever be united on this question in the future.
