Nicola Sturgeon has made a direct appeal to Labour to "join forces with us" in a bid to keep the Conservatives out of government after the General Election.
The SNP leader also assured the rest of the UK that her party would seek to "shake up" the Westminster system, despite ultimately wanting to leave the union.
Nicola Sturgeon has made a direct appeal to Labour to "join forces with us" in a bid to keep the Conservatives out of government after the General Election.
Speaking at her party's Spring conference, Sturgeon said: "If there is a hung Parliament, SNP MPs will vote to stop a Tory Government even getting off the ground.
"I call on Labour, today, to match that pledge - to make clear that if Labour and the SNP combined have more seats than the Tories, they will join forces with us in a vote of confidence to lock David Cameron out of Downing Street," she said.
After huge cheers from the party's amassed membership, Sturgeon added: "If Labour fails to make that commitment, the only conclusion people will draw is that Labour would rather have the Tories back in power than work with the SNP."
The SNP Party conference is, according to its press office, 'the hottest ticket in town'.
Nicola Sturgeon will today pledge that her party will work with others to bring about "positive change" for ordinary people across the UK.
