Conservative MP Andrew Rosindell, secretary of the All Party Parliamentary Group on the Falkland Islands, said the referendum was an "extremely important decision" that would determine "once and for all" the wishes of the islands' inhabitants.
He added that he expected a "very similar result" to that in a referendum held by Gibraltar in 2002, in which the idea of Britain sharing sovereignty with Spain was rejected by 98.5% of residents.
It will make it clear once and for all what the Falklands Islands want for their own destiny. I hope that the Argentinian government will respect the democratic wishes of the islanders.
