DAVID Cameron will not be basing himself in Scotland in the last two weeks of the referendum campaign, No 10 has made clear, but the Prime Minister will be campaigning hard in the final push to polling day on September 18.

And while one senior Liberal Democrat source suggested Scots would see the Conservative leader "about the right amount" in the days before the vote, another made clear senior Lib Dem ministers had not tried to dissuade Mr Cameron from spending the last few weeks north of the border.

A Lib Dem Cabinet Minister was quoted as saying: "We have been told he wants to spend as much as possible of the last two weeks in Scotland, especially if there is a clear lead for No and so he can pose as the man that saved the Union."

It was also suggested senior Lib Dem figures privately believe Mr Cameron is a huge negative. But Labour politicians have made clear they do not regard the PM as an asset to the No campaign.

Last night, a Downing Street insider insisted there was "no truth" in the claim the PM was considering basing himself in Scotland in the last fortnight of the campaign but that he would be north of the border frequently as polling day neared.
