instruction: To which town in the UK did the Ford Motor Company relocate to in 1931?
context: In 1931 the Ford Motor Company relocated from Trafford Park in Manchester, to a larger new plant in Dagenham, which was already the location of supplier Briggs Motorway Bodies. A 500-acre (200 ha) riverside site was developed to become Europe's largest car plant, a vast vertically integrated site with its own blast furnaces and power station, importing iron ore and exporting finished vehicles. By the 1950s Ford had taken over Briggs at Dagenham and its other sites at Doncaster, Southampton, Croydon and Romford. At its peak the Dagenham plant had 4,000,000 square feet (370,000 m2) of floor space and employed over 40,000 people, although this number gradually fell during the final three decades of the 20th century as production methods advanced and Ford invested in other European factories as well. Some of Britain's best selling cars, including the Fiesta, Escort, Cortina and Sierra, were produced at the plant over the next 71 years.
response: Dagenham
