North East Derbyshire is a constituency created in 1885 represented in the House of Commons of the UK Parliament since 2017 by Lee Rowley of the Conservative Party. This was the first time a Conservative candidate had been elected since 1935. The seat had been, relative to others, a marginal seat from 2005 to 2019 as its winner's majority had not exceeded 5.7% of the vote since the 23.2% majority won in that year. The seat has changed hands once since that year and is no longer marginal after the 26% majority won in 2019. History Summary of results The seat was created in the Redistribution of Seats Act 1885. Until 1910, the area was regularly represented by a Liberal MP. From the 1935 to the 2015 elections inclusive N.E. Derbyshire returned Labour candidates in succession. In 2010 and 2015 the results featured marginal majorities (a majority of relatively few percentage points between the winner's and the runner-up's tallies). The runner-up candidate from 1945 to 2015 inclusive was Conservative. The 2015 result for example gave the seat the 17th-smallest majority of Labour's 232 seats by percentage of majority. The seat was at the following election one of six gains between the two parties counterbalancing Conservative losses (the party emerged as the biggest single party by more than fifty seats and with an increased share of the vote but with a net loss of thirteen seats). Rowley's local majority was 5.7% of votes cast. Other parties In line with nationwide swing in 2015, UKIP fielded a candidate who won more than 5% of the vote therefore kept their deposit; the Liberal Democrat candidate forfeited their deposit in 2015. The Green Party fielded a candidate for the first time in 2015; the party's Kesteven forfeited his deposit. These three parties forfeited their deposits in 2017. Turnout Turnout has ranged from 58.9% in 2001 to 86.4% in 1950. Constituency profile In the 20th century, mining and associated industries were an important source of employment and primary industries for the wider economy, though the former ceased around 1970. At about the same time, some ex-mining towns like Dronfield saw much middle class commuter house building in areas like Dronfield Woodhouse; jobs were typically in Sheffield and Chesterfield. The western edge of the constituency borders the Peak District and is home to many rural villages. Boundaries 1885–1918: The Sessional Division of Eckington, and in the
