Former Prime Minister Gordon Brown is today expected to make an impassioned plea about why Labour must be elected to lead the next UK Government.
The party will be hoping his legendary, barnstorming oratory skills will powerfully set out the argument that a SNP surge will return David Cameron to Downing Street to mete out five more years of austerity.
Mr Brown, who is not standing for re-election and bringing to a close a 32-year Westminster career, was widely credited for persuading many people to reject Scottish independence in September.
He is speaking in Glasgow alongside Scottish Labour leader Jim Murphy who, ironically, is relying on Conservative support to retain his East Renfrewshire seat.
Mr Murphy is expected to say: “We’re less than 48 hours away from being able to change our country and set out on the road to a fair economy.
“We cannot gamble on ending Tory rule with a vote for the SNP.
“They plan to vote against Labour budgets and a Labour Queen’s Speech, and are planning the road to a second referendum.
“It’s the last thing working class people in Scotland need.
“Radical change can come to Scotland, with a Labour Government that will put fairness at its heart.”
Mr Murphy said the party was committed to banning exploitative zero hours contracts, raising the minimum wage, extending the living wage and introducing a mansion tax to deliver £1billion of extra investment in the NHS.
