Chipping Barnet is a constituency created in 1974 represented in the House of Commons of the UK Parliament since 2005 by Theresa Villiers of the Conservative Party. Villiers was the Secretary of State for Northern Ireland from 2012 until 2016 under the leadership of Prime Minister David Cameron before she was dismissed when the incoming Prime Minister Theresa May took office. Boris Johnson appointed her as Secretary of State for Environment, Food and Rural Affairs in July 2019 before she was sacked in February 2020. It is part of the London Borough of Barnet. Constituency profile Barnet was once an elevated narrow projection of Hertfordshire into the county of Middlesex, and consisted of an agricultural market town. The town became well connected to central London by the London Underground network and is today commuter suburbia, with many of its properties semi-detached with substantial gardens as well as having many small parks and nature reserves. The area has few tower blocks for social housing. Electoral Calculus categorises the seat with a "Kind Yuppies" demographic, indicating well-educated younger voters who could vote for either the Conservatives or Labour but opposed Brexit. Boundaries 1974–1997: The London Borough of Barnet wards of Arkley, Brunswick Park, East Barnet, Hadley, and Totteridge. 1997–2010: As above plus Friern Barnet. 2010–present: The London Borough of Barnet wards of Brunswick Park, Coppetts, East Barnet, High Barnet, Oakleigh, Totteridge, and Underhill. For the 2010 general election, following a review of parliamentary representation and as a consequence of changes to ward boundaries, the Boundary Commission for England recommended that parts of Underhill ward and Coppetts ward be transferred to Chipping Barnet from the constituencies of Hendon and Finchley and Golders Green respectively. It also recommended that a small part of Mill Hill ward be transferred from Chipping Barnet to Hendon.
