After four years on the back benches, he was appointed Secretary of State for Energy in 1987 (having been tipped as a potential Chancellor of the Exchequer), and for Transport in the July 1989 reshuffle. One of the highlights during his tenure of the latter job was announcing new main-line rail tunnels across London, called Crossrail. He resigned along with Margaret Thatcher when she was replaced by John Major, and stood down from the House of Commons at the 1992 general election.
