When Terence O'Neill became Prime Minister in 1963 he appointed Faulkner, his chief rival for the job, as Minister of Commerce. Faulkner resigned in 1969 over the technicalities of how and when to bring in the local government reforms which the British Labour government was pushing for. This was a factor in the resignation of Terence O'Neill, who resigned as Prime Minister in the aftermath of his failure to achieve a good enough result in the 1969 Northern Ireland general election.
