The constituency covers a largely residential area immediately north of Derby city centre, including some of the city's most affluent suburbs, as well as some of its council housing, though much of this is former council housing in private ownership. Unemployment is below the national average. Average incomes are above the national average.[5]
History[]
A seat contested relatively closely between the two largest parties since 1950, Derby North was held consecutively by the Labour Party's Clifford Wilcock, Niall MacDermot, and Phillip Whitehead.[n 3] At the 1979 general election, it was covered by the BBC as the bellwether seat as the 41st of 41 seats that the Conservative Party needed to win; that year it stayed under control of Labour, but the Conservatives won the election regardless. Its exit poll was a central point of discussion of the BBC's election night coverage.[6]
The Conservative Greg Knight gained the seat in 1983, and held it until 1997.[n 4]
Labour's Bob Laxton defeated Knight in 1997 and held the seat until retiring in 2010, when the seat was retained for Labour by Chris Williamson. In 2015, Amanda Solloway, a Conservative; gained the seat with a swing of 0.8%. The 2015 result gave the seat the second-most marginal majority (measured by percentage) of the Conservative Party's 331 seats.[7] Williamson regained the seat in 2017. He was subsequently suspended from the Labour Party, and was blocked in November 2019 from running as a Labour candidate at the following election;[8] he resigned from the party and stated his intention to run as an independent.[9]
