He stepped down from office at the 2005 general election, and became a life peer later that year.

He served briefly in Westminster as MP for Kincardine and Deeside, during which time he was the Liberal Democrat spokesperson on small business, before his election to the Scottish parliament in 1999.
It has recently been reported in The Scotsman newspaper that Nicol Stephen plans to seek the role of Scotland's First Minister in any coalition deal between the Liberal Democrats and other parties following the Scottish parliamentary elections in May.
ALEX SALMOND MSP
Career: Alex Salmond has been leader of the Scottish National Party since 2004, having first held the post between 1990 and 2000.
He is calling for a referendum on independence for Scotland, a pledge which forms part of the SNP campaign for the May 2007 Scottish parliamentary elections.
He has accused Gordon Brown of "morphing into an Englishman", adding: "The Chancellor may have been born Scottish but he is desperate to become an Englishman."

After graduating from the University of Strathclyde she worked as a solicitor, entering politics with her election to the Scottish parliament in 1999.
She held the posts of Scottish Conservative spokesman on economy, justice and home affairs, before becoming party leader in November 2005.
She recently spoke out against the government's proposals for nationwide road charging, saying: "This is a regressive tax which would hit households and families on the lowest incomes hardest. The Lib-Lab Pact want roads for the rich - the Scottish Conservatives want roads for the people whose taxes have already paid for them."
