Chingford and Woodford Green is a constituency in North East London represented in the House of Commons of the UK Parliament by Sir Iain Duncan Smith of the Conservative Party since its creation in 1997.

[a] The seat covers the outer London commuter suburbs of Chingford, Highams Park and Woodford with high levels of owner-occupier housing,[3] along with part of Epping Forest.

Once safely Conservative, the seat is now marginal with Labour due to young families and ethnic minority voters moving into the constituency.

[5] Before 1945, both Chingford and Woodford were part of the Epping parliamentary constituency, for which wartime Conservative Prime Minister Winston Churchill was MP.

[6] At the 2017 snap election, Duncan Smith was re-elected with a greatly reduced majority on a 7% swing to Labour, slightly more than a sixth of his 2010 margin.
