The Labour Party was re-founded in 1949 as a successor to the Labour Party founded in 1921. Paul Boffa, Leader of the Labour Party and Prime Minister since 1947, resigned and left the party because of serious disagreements with his Deputy Dom Mintoff which had led to a series of cabinet crises. Boffa formed the Malta Workers Party (MWP) while Mintoff re-organized the Labour Party as the Malta Labour Party.[citation needed]
