Leyland Motors Limited (later known as the Leyland Motor Corporation) was a
British vehicle manufacturer of lorries, buses and trolleybuses. The company
diversified into car manufacturing with its acquisitions of Triumph and Rover in
1960 and 1967, respectively. It gave its name to the British Leyland Motor
Corporation, formed when it merged with British Motor Holdings in 1968, to
become British Leyland after being nationalised. British Leyland later changed
its name to simply BL, then in 1986 to Rover Group.
Although the various car manufacturing businesses were eventually divested or went defunct due to the troubled existence of BL and its successors (Mini and Jaguar Land Rover are the two surviving organisations), the original Leyland Trucks business still exists as a subsidiary of Paccar.
