It was partly nationalised in 1975, when the UK government created a holding company called British Leyland, later BL, in 1978. It incorporated much of the British-owned motor vehicle industry, which constituted 40 percent of the UK car market, with roots going back to 1895., The Swift Motor Company made Swift Cars in Coventry , England from 1900 until 1931 . It grew progressively from James Starley 's Coventry Sewing Machine Company , via bicycle and motorised cycle manufacture . The cars ranged from a single - cylinder car in 1900 using an MMC engine , through a Swift - engined twin - cylinder 7 - horsepower light car in 1904 , and a 3 - litre model in 1913 . After WW1 a successful range was sold during the 1920s , but the Cadet of 1930 was their last vehicle as they could not compete economically with volume manufacturers such as Ford and Morris Motors ., Morris Motors Limited was a British motor vehicle manufacturer formed in 1919 to take over the assets of WRM Motors Ltd., which had been put into voluntary liquidation. Though merged into larger organisations, the Morris name remained in use until 1984 when British Leyland's Austin Rover Group decided to concentrate on the more popular Austin brand. The trademark is currently owned by the China-based automotive company SAIC after being transferred from bankrupt subsidiary Nanjing Automotive., James Starley (21 April 1831  17 June 1881) was an English inventor and father of the bicycle industry. He was one of the most innovative and successful builders of bicycles and tricycles. His inventions include the differential gear and the perfection of the bicycle chain drive., A metropolitan borough is a type of local government district in England, and is a subdivision of a metropolitan county. Created in 1974 by the Local Government Act 1972, metropolitan boroughs are defined in English law as metropolitan districts. However, all of them have been granted or regranted royal charters to give them borough status (as well as, in some cases, city status). Metropolitan boroughs have been effectively unitary authority areas since the abolition of the metropolitan county councils by the Local Government Act 1985. However, metropolitan boroughs pool much of their authority in joint boards and other arrangements that cover whole metropolitan counties, such as combined authorities., Subject: swift motor company, Relation: country, Options: (A) carbon (B) china (C) england (D) united kingdom
