SCOTTISH Labour leader Jim Murphy claimed yesterday that only his party was “big enough to kick out David Cameron” as he formally launched the party’s general election campaign.

Speaking at a Glasgow foodbank, Mr Murphy said Labour would abolish the bedroom tax, benefit sanction targets and zero-hours contracts while raising the minimum wage, extending the living wage and ending the need for foodbanks.

The East Renfrewshire MP said voters had a choice between “another five years of Tory cuts and austerity, which hurt the poorest in our community the most, or a Labour government which stands up for working-class people.

“A vote for anyone but Labour gives the Tories a better chance of hanging on and five more years of Tory misery for our poor and our vulnerable.”

SNP leader Nicola Sturgeon retorted that Labour leader Ed Miliband was “clinging to the pretence” that he could have an overall majority after the election on May 7.

Speaking to BBC Radio, Ms Sturgeon said her party was open to an arrangement with Labour and argued that many of Mr Miliband’s backbenchers would support SNP policies such as ending austerity and scrapping Trident.

“The bottom line here is, if Scotland wants to have that influence, that clout in Westminster, the only way get it is to vote SNP,” she said.

Only 3.4 per cent of No voters in September’s Scottish independence referendum were swayed by the “vow” of more powers by unionist parties, researchers have found.

However 41.3 per cent of Yes voters believe people voted No because “Westminster leaders misled Scots over more powers,” according to the Edinburgh University report.
