The predecessor unions to the National Union of Railwaymen and the National Union of Seamen were founding members of the original Labour Representation Committee and after its creation the RMT became a prominent voice on the left of the Labour Party. In 2003 some Scottish branches of the RMT voted to donate some of their funds to the Scottish Socialist Party in protest against the policies of Tony Blair and New Labour, such as not renationalising the railways. This led the Labour Party to expel the union in early 2004 for breaching its rules.
