It is expected that Ford will announce the end of production at its huge Dagenham car plant later this month. The final announcement will come when the world's second largest auto manufacturer outlines downsizing plans for its production facilities throughout Europe. Cars have been rolling off the Dagenham production line since Henry Ford opened the factory in 1931. At its peak, Ford employed some 30,000 workers at the company's largest factory in Britain, situated on the Thames estuary east of London. The plant has been scaled down over an extended period, but until recently it provided employment for 7,000 workers, over a quarter of the company's British workforce.
