List of elected British politicians who have changed party affiliation information
This list is incomplete; you can help by adding missing items. (February 2011)
This is a list of members of the House of Commons of the United Kingdom, the House of Lords, British members of the European Parliament, members of the British devolved legislatures (such as the Scottish Parliament, Senedd, and Northern Ireland Assembly) and Police and Crime Commissioners (PCCs) who have changed their party affiliation (i.e. abandoning a previous party membership to take up a new one) or who have resigned from, been suspended from or been expelled from their previous party affiliation, making them independents. When a member of a legislature switches from one party to another, this is called crossing the floor. The list details the dates, members involved, previous and new party affiliations, and an explanation for their switch.
