History of boundaries From 1885 to 1983, Louth and Horncastle both existed as separate constituencies. Then in 1983, Horncastle was moved into the new seat of Gainsborough and Horncastle, while Louth was moved into the newly formed East Lindsey constituency. These boundaries remained the same until 1997, when the current Louth and Horncastle constituency was formed. Constituency profile This large stretch of Lincolnshire coastline includes the seaside resorts of Mablethorpe and Sutton-on-Sea, this immediate coastline has a minority of small output areas with severe deprivation following the decline of the tourism industry apart from holiday cottages, being further north than popular family resorts in Skegness. The seat's eponymous towns of Louth and Horncastle lie inland amid a rural area of the Lincolnshire Wolds where farming is an important sector, with most constituents on modest to mid-level income and low unemployment. History The seat was created in 1997. Conservatives have been dominant in the area for decades, the closest result was in 1997, when a Labour Party candidate came the closest of any opponents to being elected. Members of Parliament The MP for this seat is Victoria Atkins. She succeeded Peter Tapsell at the 2015 general election. He previously represented the predecessor seats of East Lindsey and Horncastle from 1966 to 1997, and before that represented Nottingham West from 1959 to 1964 before being defeated
