 The business voters were a type of plural voter which when abolished by the Representation of the People Act 1948 meant the City became immediately under-sized in electorate, akin to the least-worst examples of pre-1832 "rotten and pocket boroughs".In 1950 the area was merged for Parliamentary purposes with the eldest parts of the neighbouring City of Westminster, to form the seat Cities of London and Westminster.The pre-1900 heavily-subdivided city became simplified for the period 1907 and 1965 into one civil parish, before in that year this level of local government complication was taken away.
