In 1906, the LRC changed its name to the "Labour Party", amalgamating with the ILP. In that same year, MacDonald was elected MP for Leicester along with 28 others, and became one of the leaders of the Parliamentary Labour Party. These Labour MPs undoubtedly owed their election to the 'Progressive Alliance' between the Liberals and Labour, a minor party supporting the Liberal governments of Henry Campbell-Bannerman and H. H. Asquith. MacDonald became the leader of the left wing of the party, arguing that Labour must seek to displace the Liberals as the main party of the left.
