Why was Malta’s self-government withdrawn in 1933?

Malta’s self-government, which had been granted on a dyarchical basis in 1921, was withdrawn by Britain in 1933 primarily due to Maltese resistance against the colonial administration's efforts to replace Italian with English as the official language of the territory. Following the revocation of this agreement, the island reverted to a strictly colonial regime, concentrating full governing power in the hands of the British governor.1
