Britain's dead-heat election 'down to the wire' on polling day
Britons went to vote on Thursday in the tightest election for decades; one that could cause government gridlock, push the world's fifth-largest economy closer to leaving the European Union and stoke a second attempt by Scotland to break away.
Final opinion polls showed Prime Minister David Cameron's Conservatives and Ed Miliband's opposition Labour Party almost in a dead heat, indicating neither will win enough seats for an outright majority in the 650-seat parliament.
