Northampton was a parliamentary constituency (centred on the town of Northampton), which existed until 1974. It returned two Members of Parliament (MPs) to the House of Commons of the Parliament of the United Kingdom until its representation was reduced to one member for the 1918 general election. The constituency was abolished for the February 1974 general election, when it was replaced by the new constituencies of Northampton North and Northampton South. A former MP of note for the constituency was Spencer Perceval, the only British Prime Minister to be assassinated.
