ALEX SALMOND has said the SNP is preparing to shake Westminster “to its foundations” after the General Election.

With polls indicating a huge swing to the nationalists in Scotland, the former First Minister said Labour would find it “very difficult” to refuse the party’s support in the event of a hung parliament.

He was speaking as extracts from The Dream Shall Never Die, his referendum diary looking back on the campaign for independence, were published in the Scottish Sun on Sunday.

Looking forward to the outcome of the vote on

May 7, Salmond, who is standing in the Gordon seat, told the newspaper: “A coalition with Labour is unlikely, confidence and supply is likely and vote-by-vote support is probable. They can refuse our approach but they would find it very difficult.”

He added: “We’ll shake Westminster to its foundations.”

His book criticises Prime Minister David Cameron as well as the Treasury and the BBC for their conduct during the referendum.

Salmond said he was “disgusted” with Cameron’s decision to link further devolution for Scotland with English votes for English laws in the wake of the No vote on September 18.

He branded the Prime Minister “a Tory toff on a day trip” for his interventions in the debate and lambasting the “imperial bias” of broadcasters.
