>> After months of fierce debate and political in-fighting, it's time for Britain to decide its future in the EU. Polls are now open to voters across the United Kingdom. The question they face, a simple yes or no. Should the United Kingdom remain in the European Union or give up its membership?

And that's because while the question might be simple, the consequences are anything but. Guy Faulconbridge is Reuters' UK Bureau Chief.>> So after 10 o'clock London time when the polls close, the 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 yes-no percentages for each of those 382 different areas.>> Prime Minister David Cameron promised a referendum in the run-up to last year's general election.>> It is time for the British people to have their say. He's led the remain campaign since announcing the date in February, starting four months of increasingly acrimonious debate often among his fellow conservatives.

So some people feel that the political discourse has been debased to some extent.>> Ballot boxes close at 10 PM on Thursday, a result expected within hours.
Britain could be waking up to a very new dawn on Friday morning.
