«The UKIP threat is draining Tory support in
key marginal seats so much that the party could let Ed Miliband into Downing Street, according to a poll released today by Lord Ashcroft, former deputy chairman of the Conservative party.
This is a swing of 6 points (the equivalent of a Labour lead of about 5 points in a national poll),
so suggests Labour may be doing somewhat better in
key marginal seats than in the country as a whole.
