As postmaster general he saw the introduction of the Premium Bond scheme and of postcodes. His period as Minister of Transport was controversial. He both oversaw significant construction (he opened the first section of the M1 motorway) and the closure of a considerable portion of the national railway network with the Beeching cuts. His involvement in the road construction business Marples Ridgway, of which he had been managing director, was one of repeated concern regarding possible conflict of interest.
