Hitting the target, Archer.

Mr Smith is hardpressed not to agree with Mr Archer's comments in the Scotland On Sunday about Wendy Alexander MSP becoming Leader of the Scottish Labour Party, "Alexander isn't the solution, she's part of the problem."

Mr Archer should know. As well as being a former adviser to SNP Leader Alex Salmond, he was also a sixteen year member of the Scottish Labour Party and Labour Councillor in Govan until he defected to the SNP. His other claim to fame is that he stood against former Labour MP Ernie Ross in Dundee in 2001 ... and didn't manage to beat him.
