London Borough of Epsom and Banstead

This proposed borough includes the existing Surrey borough of Epsom and Ewell as well as parts of the Surrey boroughs of Mole Valley, "Reigate and Banstead" and Tandridge. The name comes from Epsom and Ewell as well as the Banstead in the existing Reigate and Banstead borough. It includes all the parts of these boroughs that lie within the M25 as well as Leatherhead, Fetcham and Great Bookham which form a sort of urban peninsula that stretches from the M25 into the Surrey green belt. The parts of the Mole Valley, "Reigate and Banstead" and Tandridge boroughs outside of my proposed borough will be merged into a new borough tentatively named East Surrey.
The proposed boundaries are shown in the map below in the pink. I estimate the population of this borough to be 170,000.

Towns and villages in the Borough:

Epsom, Ewell, Banstead, Tadworth, Caterham, Warlingham, Ashtead, Leatherhead, Great Bookham, Fetcham, Woldingham

Home to Epsom Downs Racecourse.
Epsom and Ewell Borough council is run by the Epsom and Ewell Resident's Association not one of the main political parties.
It contains a large number of golf courses, as well as a few country parks and woodland.
