[2] Penrith and The Border was first contested in 1950 since which it was generally a safe Conservative seat and on rare occasions a marginal.

1983–1997: The District of Eden wards of Alston Moor, Appleby, Appleby Bongate, Askham, Brough, Crosby Ravensworth, Dacre, Eamont, Greystoke, Hartside, Hesket, Kirkby Thore, Kirkoswald, Langwathby, Lazonby, Long Marton, Lowther, Penrith East, Penrith North, Penrith South, Penrith West, Skelton, Ullswater, and Warcop, the City of Carlisle wards of Arthuret, Brampton, Burgh, Dalston, Great Corby and Geltsdale, Hayton, Irthing, Lyne, St Cuthbert Without, Stanwix Rural, and Wetheral, and the District of Allerdale wards of Aspatria, Boltons, Marsh, Silloth, Tarns, Wampool, Warnell, Waver, and Wigton.

The constituency tended to have modest incomes,[3] low unemployment[4] and a rate of dependency on social housing lower than urban centres.

[5] The seat was represented for nearly three decades by William Whitelaw, who served as a cabinet minister in various capacities during Conservative governments of the 1970s and 1980s and later joined the House of Lords.

His successor, the former Conservative Chief Whip and junior minister, David Maclean, sat as MP from 1983 to 2010, when he stood down due to the state of his health; he was diagnosed with multiple sclerosis in 1996.
