David Murray John, Swindon's town clerk from 1938 to 1974, is seen as a pioneering figure in Swindon's post-war regeneration: his last act before retirement was to sign the contract for Swindon's tallest building, which is now named after him. Murray John's successor was David Maxwell Kent, appointed by the Swindon/Highworth Joint Committee in 1973: he had worked closely with Murray John and continued similar policies for a further twenty years. The Greater London Council withdrew from the Town Development Agreement and the local council continued the development on its own.
