Boundaries

The constituency is composed of the following electoral divisions of County Durham (as they existed on 1 December 2020):

• Aycliffe East; Aycliffe North and Middridge; Aycliffe West; Bishop Middleham and Cornforth; Chilton; Coxhoe; Ferryhill; Sedgefield; Spennymoor; Trimdon and Thornley (polling districts SKB, SLA, SLB, SMB and SMC); Tudhoe.^[4]

The seat is made up of the bulk of the abolished constituency of Sedgefield, expanded to include Spennymoor and Tudhoe from Bishop Auckland, and Coxhoe from City of Durham.^[5]

History

The seat is the successor to Sedgefield, most famously represented by former Labour Prime Minister Tony Blair from 1983 to 2007; he led a successful campaign for his party to win the 1997 general election in a landslide and thereafter served for ten years as Prime Minister, resigning as the MP for Sedgefield on the same day as he resigned as prime minister.^[6] This triggered a by-election, which was won by Labour's Phil Wilson. In 2019, Sedgefield was gained by the Conservatives for the first time since 1935, a result which would have been replicated if the new seat of Newton Aycliffe and Spennymoor had existed then.

The incumbent MP for Sedgefield, Paul Howell, stood for re-election in the new seat in 2024, but was beaten into third place by Reform UK, with Labour's Alan Strickland effectively regaining the seat with a 22.2% majority.
