A spokesman for the Liberal Democrat leader Nick Clegg claims he is confident the party can take seats off Labour and "particularly" the Tories at the next general election, expected to be in 2015.
They dismissed polling by former Conservative donor Lord Ashcroft suggesting the party could lose 10 constituencies to Labour - pointing out that the peer's research predicted they would lose Eastleigh.
The spokesman also played down the idea that Business Secretary Vince Cable's call for higher capital spending funded by more borrowing was part of efforts to differentiate the Lib Dems from their coalition partners.
