Lib Dems and Labour are neck-and-neck across Yorkshire with the Tories pushed into third place, according to the latest regional poll.

Labour is down two points compared with last week to 32, with the Lib Dems up seven to 32. The Conservative vote continues to be squeezed, losing five points to put them third on 28. Other parties, which includes the BNP, the independents, UKIP and the Green Party are on seven, down two.

The YouGov/Politics Home poll of 998 people across the region has put the Lib Dems up 12 points in two weeks after the first televised leaders’ debate where Nick Clegg swept to popularity.

As Cleggmania continues, polling experts have now said, based on the most recent clutch of polls, the election is still a “genuinely close” three-horse race.

Across the country the Tories lead on 33, Lib Dems on 30 and Labour third on 28.

The Lib Dems’ biggest successes have been in the North East, the East Midlands and Wales. In each of these regions they have gained more than ten percentage points since last week.

Support for the Conservatives has remained constant since last week in Wales, but has fallen in every other region. Support for Labour has also fallen across the country, with the party’s biggest losses in Wales and the North East.

A hung Parliament is the most likely outcome next Thursday if the polls continue as they have been.

For the second time this week the Tory high command has pulled a planned party election broadcast at the last minute to replace it with one concentrating on the dangers of a hung parliament as David Cameron fails to gain enough popularity to secure an outright majority.

There was also anger in the Labour ranks after Mr Clegg made clear that he would be prepared to work with the party, even if it had slipped to third in the popular vote, provided it got rid of Mr Brown.

Schools Secretary Ed Balls said: “Nick Clegg at the moment is giving the impression that he himself can decide who will be Prime Minister.

“That is decided by the British people in the ballot box. You cannot give the impression that politics is like a game of trumps where you can play your hand and bluff away. The hands have not yet been dealt.”
