Municipal Borough of Leyton

From the Wikipedia article at :

Leyton was a local government district in southwest Essex, England, from 1875 to 1965. It included the neighbourhoods of Leyton, Leytonstone and Cann Hall. It was suburban to London, forming part of the London postal district and Metropolitan Police District. It now forms the southernmost part of the London Borough of Waltham Forest in Greater London.

In 1965 it was abolished by the London Government Act 1963 and its former area transferred to Greater London from the administrative county of Kent. Its former area was combined with that of other districts to form the present-day London Borough of Bexley.
