Britain's prime minister David Cameron cast his vote on Thursday in what is the country's most unpredictable election in decades.
Walking with his wife Samantha, Cameron smiled for photographers as he arrived at a polling station in Witney in his constituency.
Cameron's Conservatives and Ed Miliband's opposition Labor Party have been neck and neck in opinion polls for months, indicating neither will win enough seats for an outright majority in the 650-seat parliament.
Cameron has been campaigning with the message that any alternative to his Conservative party would spell chaos for the country. Labor's message is that it is the only party which will fight for working people.
If neither wins an overall majority, talks will begin on Friday with smaller parties in a race to strike deals. That could lead to a formal coalition, like the one Cameron has led for the past five years with the centrist Liberal Democrats. Or it could produce a fragile minority government making trade-offs to guarantee support on key votes.
