British voters head to the polls Thursday in one of the tightest elections in recent decades, with Prime Minister David Cameron’s Conservatives neck and neck with Ed Miliband’s opposition Labour Party. Opinion polls have been too close to call to indicate which major party will secure enough seats for an outright majority in the 650-seat parliament. If neither party wins overall, smaller parties will begin talks Friday to form a coalition like the one Cameron has led with the centrist Liberal Democrats for the past five years.
