Mintoff's strong position and ambition led to a series of Cabinet crises. A split in the Labour Party came about when Boffa, who was ready for compromise and moderation with the colonial authorities, resigned and formed the Malta Workers Party and Mintoff refounded the Labour Party as the "Malta Labour Party" of which he assumed leadership. The split resulted in the weakening of both parties and it was not until 1955 after remaining out of government for three consecutive legislatures, that the Labour Party was elected to office with Mintoff as Prime Minister. This government's main political platform – integration with the UK – led to a deterioration of the Party's relations with the Catholic Church, leading to interdiction by the Church which resulted in voting Labour being declared a mortal sin leading all who defied the Church to be informally known as "Suldati tal-Azzar" (Soldiers of Steel). The Labour Party lost the subsequent two elections in 1962 and 1966 and boycotted the Independence celebrations in 1964 due to disagreements with the Independence agreements which still gave a good amount of power to the British Government.
