The incumbent British Prime Minister David Cameron put on a brave face as he turned out to vote in the UK’s most unpredictable election in decades.
Polling stations opened at 7 o’clock in the morning local time and close at 10 pm Thursday night (11 pm CET).
The first indication of whether or not Labour’s Ed Miliband has a chance of getting into Downing Street will come shortly afterwards.
Three of the main TV broadcasters will release a forecast based on exit polls carried out across the country.
Threatening to deliver surprises in this ballot are the fringe parties, such as the UK Independence Party of Nigel Farage, or the Scottish National Party led by Nicola Sturgeon.
If, as expected, neither the Conservatives nor Labour wins an overall majority, talks would be held with the smaller parties.
There could be a formal coalition, like the one that Cameron has led for the past five years with Nick Clegg’s Liberal Democrats.
But there could also be a fragile minority government, or even a period of political deadlock.
