James Sillars is a Scottish politician. He was married to Margo MacDonald until her death in 2014.Early lifeSillars was born in Ayrshire, Scotland. His early working life involved him following his father into working on the railways, then joining the Royal Navy, before becoming a fireman. It was as a fireman that he became more active politically, through the Fire Brigades Union (FBU) and later with the Scottish Trades Union Congress (STUC).Labour MPSillars was elected at a by-election in 1970 as Member of Parliament (MP) for South Ayrshire constituency, representing the Labour Party. He became well known as an articulate, intellectual left-winger, strongly in favour of the establishment of a devolved Scottish Assembly.SLP breakawayIn 1976 he led a breakaway Scottish Labour Party (SLP). The formation of the SLP was inspired primarily by the failure of the then Labour Government to secure a Scottish Assembly. Sillars threw himself into establishing the SLP as a political force, but ultimately it collapsed following the 1979 General Election. At that election the SLP had nominated a mere three candidates (including Sillars who was attempting to hold on to his South Ayrshire seat). Only Sillars came remotely close to winning and it was this failure to secure a meaningful share of the vote that prompted the decision to disband.
