Charrington Brewery was founded in Bethnal Green, London, in the early 18th century by Robert Westfield. In 1766, John Charrington joined the company, which then traded as Westfield, Moss & Charrington from the Anchor Brewery in Stepney. It merged with United Breweries of London in 1964, and with Bass Brewery in 1967 to become the largest UK brewing company, Bass Charrington. The brewing operations of the company were bought by Interbrew (now Anheuser-Busch InBev) in 2000, while the retail side (hotel and pub holdings) were renamed Six Continents. In 2003, Six Continents split into a pubs business, now known as Mitchells & Butlers, and a hotels and soft drinks business, now known as InterContinental Hotels Group.
