The constituency mainly consists of low-income social housing and former social housing built to decant the residents displaced by post-war slum clearance in Liverpool. It includes Huyton to the south (once represented by Prime Minister Harold Wilson) and Kirkby to the north. Between them is the green space of Knowsley Hall and Park, the ancestral home of the Earls of Derby and the site of Knowsley Safari Park. In 2010, The Guardian summarised the area as "One of the most deprived areas in the country. The new parliamentary constituency folds in Knowsley North and Knowsley South."[2]
It ranked foremost by party majority in 2017, where it was followed directly by East Ham and 28 other seats won by Labour candidates, after which followed North East Hampshire.[6] It achieved the highest majority for any British Member of Parliament since the advent of universal suffrage, with Labour winning with a majority of 42,214 votes, surpassing the 36,230-vote majority held by then-ConservativePrime MinisterJohn Major in his Huntingdon constituency in 1992.
