The British Virgin Islands elects on territorial level a unicamerallegislature. The House of Assembly (formerly named the Legislative Council prior to the 2007 election) has 15 members, 13 members elected for a four year term, 9 of them in single-seat constituencies and 4 at large. The Attorney General and one speaker chosen from outside the council also serve on the Council.
The British Virgin Islands has a two-party system, which means that there are two dominant political parties, with extreme difficulty for anybody to achieve electoral success under the banner of any other party.
Elections are held every four years. The last election was in 2007. The system of elections is very similar to that of Westminster. The parties nominate candidates on a nomination day, then the election is held several weeks later.
