The Falkland Islands are divided into two constituencies, Camp and Stanley. Camp returns three elected members and Stanley returns five elected members using block voting. The Stanley constituency consists of the area within 3.5 miles of the spire of Christ Church Cathedral, Stanley, while the Camp constituency consists of the rest of the Territory. The Constitution allows for the constituencies and their boundaries to be amended, but such an amendment must be agreed to by two-thirds of the vote in a referendum of the islanders.
