Only parties registered with the Electoral Commission are shown here; see the Electoral Commission's Register of Political Parties. Parties' full legal names are shown here, with shortened variants shown in other places across the site, where appropriate.
Due to the relatively infrequent changes in registered parties, this information is updated manually, which can introduce delays. If this list is significantly out of date, you can lodge a correction request here.
The number of seats shown for each party is calculated from the current composition of Parliament, and may not be the same as the number of seats that the party won at the last election.
