Derby city centre has been in this constituency since 1974; from 1950 it had been in Derby North. The proposals made by the Boundary Commission in 2016 for new constituencies would have seen the wards Aston, Chaddesden, Spondon and Oakwood move into the seat while the wards Arboretum, Normanton and Blagreaves would move to the seat of Derby North. This would notionally make the seat a Conservative seat. If implemented, this would be the first time the city centre has been in Derby North since 1974. Members of Parliament Constituency profile The constituency takes in Derby city centre including much of its varied income inner-city, a narrow majority of which used to be local council-built however which is offset by conservation areas including beside Derby Cathedral and Derby Catacombs. The remainder of the seat is generally more affluent suburbs, and much of the engineering industry traditionally associated with the city. History The constituency was created in 1950, when the former two-seat constituency of Derby was split into two single-member seats. Unlike the Derby North seat, this seat has to date been a Labour Party seat. A notable former MP for the seat was its first incumbent, Philip Noel-Baker of the Labour Party. He served as a Cabinet minister in
