Orpington was an electoral division for the purposes of elections to the Greater London Council. The constituency elected one councillor for a four-year term in 1973, 1977 and 1981, with the final term extended for an extra year ahead of the abolition of the Greater London Council.
It was planned to use the same boundaries as the Westminster Parliament constituencies for election of councillors to the Greater London Council (GLC), as had been the practice for elections to the predecessor London County Council, but those that existed in 1965 crossed the Greater London boundary. Until new constituencies could be settled, the 32 London boroughs were used as electoral areas. The London Borough of Bromley formed the Bromley electoral division. This was used for the Greater London Council elections in 1964, 1967 and 1970.
The new constituencies were settled following the Second Periodic Review of Westminster constituencies and the new electoral division matched the boundaries of the Orpington parliamentary constituency.[1]
It covered an area of 7725hectare in 1973. Revisions to ward boundaries in the London Borough of Bromley changed the area of the division to 7688hectare for the 1977 and 1981 elections.
The Orpington constituency was used for the Greater London Council elections in 1973,[2] 1977[3] and 1981.[4] One councillor was elected at each election using first-past-the-post voting.[5]
The fourth election to the GLC (and first using revised boundaries) was held on 12 April 1973. The electorate was 65,228 and one Conservative Party councillor was elected. The turnout was 53.6%. The councillor was elected for a three-year term. This was extended for an extra year in 1976 when the electoral cycle was switched to four-yearly.[6]
The fifth election to the GLC (and second using revised boundaries) was held on 5 May 1977. The electorate was 66,356 and one Conservative Party councillor was elected. The turnout was 54.1%. The councillor was elected for a four-year term.
The sixth and final election to the GLC (and third using revised boundaries) was held on 7 May 1981. The electorate was 68,401 and one Conservative Party councillor was elected. The turnout was 49.9%. The councillor was elected for a four-year term, extended by an extra year by the Local Government (Interim Provisions) Act 1984, ahead of the abolition of the council.
