Ashcroft’s poll of Lib Dem battleground seats: incumbency is alive and well but 2015 will be a survival election for the party

Tory peer and pollster Lord Ashcroft has published his latest set of constituency findings.

Of these, 2 are Lib Dem targets, 15 the party is defending against the Tories, and 5 against Labour. You can see the full results here .

Here are the headline findings:

  • Of the 20 Lib Dem-held seats polled, the Lib Dems would retain just 6.
