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.
Scottish Labour leader Jim Murphy claims "no-one will be fooled" by Nicola Sturgeon's claim her party will help "shake-up" Westminster to the benefit of the rest of the UK.
In a response to the SNP leader's party conference speech, Murphy added that Sturgeon's plans to fight austerity ignored "the austerity max that would be inflicted on Scotland" if the country achieved her party's aim of fiscal independence.
And after Sturgeon urged Labour to "join forces" with the SNP to keep the Conservatives out of power after the General Election, Murphy responded: “Despite all the cheering and backslapping the facts remain only Labour or the Tories can form the next UK government.
"Any seat taken from Labour by the SNP or anyone else simply helps David Cameron to stay in power."
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.
