Southampton, Itchen is a constituency represented in the House of Commons of the UK Parliament since 2015 by Royston Smith, a Conservative member of parliament. Discounting the Speaker (of the House of Commons) returned in the early 1970s in two elections, local voters have elected the MP from only two parties alternately for various periods, with one party reaffiliation (defection) between elections when the Labour Party split in the 1980s.
