Slough was transferred to Berkshire in the 1974 local government reorganisation. The old Municipal Borough was abolished and not deemed part of an urban conglomeration, replaced by a non-city type second-tier authority (Non-metropolitan district), which was however made a Borough by the town's second Royal Charter. Britwell and Wexham Court became part of Slough at this time, with their civil parish councils. On 1 April 1995, the Borough of Slough expanded slightly into Buckinghamshire and Surrey, to take in Colnbrook and Poyle and merged their civil parish councils.
