Mitcham was a constituency comprising the emerging Mitcham, Wallington and Beddington suburbs of South London and until 1945 that of Carshalton, its largest of the area's four traditional divisions, in its south-west. It returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom by the first past the post system. It was created for the 1918 general election from part of Wimbledon when it reached southwards up onto the North Downs, further south than Croydon South, and was abolished for the February 1974 general election. Two of its MPs became Home Secretary, one after changing seat of candidature, on boundary reforms.
