Falkland Islands
The Falkland Islands are divided into two constituencies, the Camp and Stanley which return three and five members respectively to the Legislative Assembly. The Camp constituency includes any part of the Falklands which is not within the boundaries of the Stanley constituency (which are defined by a 3.5 mile radius from the cathedral spire).
A referendum had been held in 2001 in which both Camp and Stanley voters rejected a change to a single constituency.
The Constitution now specifically allows for the constituencies and their boundaries to be amended, but such an amendment must be suppored in a referendum and, as a protection, there must be a two-thirds majority in each constituency.
A further referendum was held on 3 November 2011: Stanley voters narrowly supported a single constituency (but not with a two-thirds majority) and Camp voters emphatically rejected a single constituency. (Mercopress report on the 2011 referendum result)
