Swindon, UK: For 15 hours on May 7, more than 30 million Britons will vote on a new government of the United Kingdom.

And given the way the opinions polls show support for the main parties, those 30 million Britons could be back repeating the exercise in six months time.

"The last thing Britain needs is a second election before Christmas,” Liberal Democrat leader Nick Clegg said on Tuesday. But with both David Cameron's Conservatives and Ed Miliband's Labour in a virtual dead heat going into Thursday vote, that second election is looking all the more likely.

Labour and Conservatives are at about 34 per cent support – enough to make them the two largest parties in a new fractured parliament – but each at least 20 seats short of an outright majority.

Speaking at a rally in Cardiff on Tuesday, Clegg said that any attempt by Cameron or Miliband to lead a minority government in the House of Commons would be shambolic and doomed to failure.

Oh no, not another election?” James Coombes told Gulf News here yesterday evening as Britons' began to realise that the campaigning may begin again in months. “All we've heard for the past six months is this election. And now we'd have to go through it all over again? I don't think voters would like that.”

Adding fuel to the fire, the anti-European Union United Kingdom Independence Party said it wanted a referendum on Britain and the EU by the end of this year as a condition of supporting any new coalition.
