Alex Salmond was leader of the SNP for 20 years. His first term was from 1990 to 2000, and his second term was from 2004 to 2014.
He was First Minister of Scotland from 2007 to 2014.
The day after Scotland voted No to independence in a referendum on 18 September 2014, Salmond announced his intention not to stand for reelection as party leader, and to resign as First Minister.
Following an uncontested leadership election, Salmond was replaced on 19 November by his then deputy Nicola Sturgeon.
He is running to be MP for the constituency of Gordon. He has been an MP before, for Banff and Buchan, between 1987 and 2010.
