The Local Government Boundary Commission for England was established by the "Local Government Act 1972" to review periodically the boundaries of Greater London and the London boroughs. The first review of boundaries commenced on 1 April 1987 and reported in 1992. Following the review a series of relatively minor adjustments were made to borough boundaries, for example uniting the whole of the Becontree estate in Barking and Dagenham. The commission noted that many of its recommendations were strongly opposed and were not implemented. The boundary of the City of London with adjacent boroughs was adjusted to remove some anomalies.
