At the 1922 election, Labour replaced the Liberals as the main opposition party to the Conservative government of Stanley Baldwin, making MacDonald Leader of the Opposition. By now, he had moved away from the Labour left and abandoned the socialism of his youth: he strongly opposed the wave of radicalism that swept through the labour movement in the wake of the Russian Revolution of 1917 and became a determined enemy of Communism. Unlike the French Socialist Party and the Social Democratic Party of Germany, the Labour Party did not split and the Communist Party of Great Britain remained small and isolated.
