The fifth election to the Greater London Council (GLC) was held on 5 May 1977. The Conservatives, led by Horace Cutler, gained control of the council from Labour.
Electoral arrangements
The GLC was elected from 92 single-member electoral divisions which were identical with the Parliamentary constituencies in Greater London. The election date was fixed by section 43 of the Local Government Act 1972 as the first Thursday in May. Councillors had been elected for a three-year term at previous elections, with those elected in 1973 having their terms extended to four years in 1976. From the 1977 election councillors were elected for a four-year term. All aldermen went out of office in 1977 and no further aldermen were elected by the council.
Results
The Conservative Party won a majority of seats at the election. The Liberal Party lost both of its councillors.
