British voters are voting in a close election that could oust Prime Minister David Cameron from office.
Public opinion studies show that 33 percent of British voters support Mr. Cameron’s Conservative Party. The Labor party, led by Ed Milliband, is only one point behind.
Observers are calling the election Britain's most unpredictable and consequential in a generation.
Mr. Cameron has promised to hold a referendum if he is re-elected. The referendum will ask if Britain should remain in the 28-nation European Union.
