The area in the seat, remaining a combination of urban, suburban and a small rural population, has been gradually reduced through contribution to new seats, their county designation later being changed in 1965 to become part of the new county of Greater London, which adjoins. These seats are Bexley, created in 1945 and Erith & Crayford, created in 1955.
