The Scottish Labour Party (SLP) was formed on 18 January 1976 as a breakaway from the UK Labour Party, by members disaffected with the then Labour Government's failure to secure a devolved Scottish Assembly, as well as with its social and economic agenda. The formation of the SLP was led by Jim Sillars, then MP for South Ayrshire, John Robertson, then MP for Paisley and Alex Neil, the UK Labour Party's senior Scottish researcher.
