By Jason Groves - Deputy Political Editor, Daily Mail Billionaire former Tory chairman Lord Ashcroft has released a series of polls carried out in key swing constituencies Labour is tightening its grip on key election battlegrounds across the country as Tory voters desert to Ukip, according to a major new poll. The survey of eight Tory-held marginal constituencies shows that each one would fall to Labour if an election were held tomorrow. And polling in four Labour-held marginal seats suggests only one would be a close contest, with Labour comfortably holding the other three. The study, conducted by former Tory treasurer Lord Ashcroft, suggests David Cameron still has a mountain to climb in order to stay in Number 10 next year.
