On 1 April 1974, Berkshire's boundaries changed under the Local Government Act 1972. Berkshire took over administration of Slough and Eton and part of the former Eton Rural District from Buckinghamshire. The northern part of the county became part of Oxfordshire, with Faringdon, Wantage and Abingdon and their hinterland becoming the Vale of White Horse district, and Didcot and Wallingford added to South Oxfordshire district. 94 (Berkshire Yeomanry) Signal Squadron still keep the Uffington White Horse in their insignia, even though the White Horse is now in Oxfordshire. The original Local Government White Paper would have transferred Henley-on-Thames from Oxfordshire to Berkshire: this proposal did not make it into the Bill as introduced.
