The SNP may let the Conservatives back in next week, Ed Miliband claimed last night.
As post-election talks dominated the campaign trail, the UK Labour leader repeated his assertion from Thursday night that he will never work with the SNP.
The reason was “principled”, he said, because the SNP were set on breaking up the UK not working together for the benefit of everyone.
Mr Miliband was in Glasgow last night for an election rally to kick off the last weekend of campaigning.
He told the audience he had “clear message” for Scottish voters: “Don’t gamble with the SNP when you can guarantee change with Labour.”
First Minister Nicola Sturgeon said voters will never forgive Labour if their refusal to deal with the SNP means another Conservative government.
But Mr Miliband said: “I will never put the Tories into government. I have spent my entire political career fighting them.
“But the tragedy is that the SNP may very well might let the Tories in. That’s what could happen if the Tories are the largest party.
“But I am also clear there will be no deal, no pact, no coalition, no tie-in with the SNP.
“And I don’t say that for tactical reasons. I’m advocating this for principled reasons.
“We cannot do a deal with a party that wants to break up the UK when we want to build it up.
“We believe in the principles of sharing and solidarity that under-pin the partnerships of four nations that is the modern UK.”
Mr Miliband said solidarity and sharing was the essence of Labour’s belief in social justice, with each helping others in times of stress and those “with the broadest shoulders” helping those with the greatest need, when and wherever that need was greatest.
“So we cannot deal with a party that promises to end the sharing and throw solidarity to the winds,” he said.
“The very sharing and solidarity that is the rock of social justice upon which we stand.
“If we set England against Scotland, if we set any part of our country against another it does not help working people, it harms working people.”
Mr Miliband said Nationalism never built a school, lifted people out of poverty, created the welfare state and the NHS.
“There is only one thing the SNP want and that’s another referendum. That’s their priority, that’s their promise but it is not ours,” he said.
