A new poll suggests Labour and the Liberal Democrats are both facing potential general election disaster in Scotland.
The survey for STV suggests if there were an election tomorrow, the SNP would register a massive landslide, winning 54 of the 59 Scottish seats up for grabs.
Jim Murphy MP has announced he is to stand as the next leader of the Scottish Labour Party in a bid to become the First Minister.
The East Renfrewshire MP said: "I'm standing for First Minister of Scotland and I intend to win.
"I want to bring Scotland back together after the referendum. There is so much to be proud of in Scotland but so much we have to change.
"I've travelled to every part of our country and I know that people want us to get on with tackling poverty and increasing prosperity. As leader of Scottish Labour and as First Minister of Scotland that is exactly what I will do."
He will launch a formal campaign later this week and will face MSPs Neil Findlay and Sarah Boyack in the race to replace Johann Lamont, who resigned on Friday with a stinging attack on UK Labour colleagues who she accused of treating Scotland as a "branch office".
