In 1983 parliamentary boundaries were realigned to those of the local government districts created in 1974: the town of Dorking became part of Mole Valleydistrict, and just over half of the previous area was transferred to the Mole Valley seat for national elections which took in territory to the north from elsewhere. Horley transferred to the redrawn Reigate seat.
