Not a lot of people know that John Lennon and Yoko Ono were married in Gibraltar, or that Prince Charles started his honeymoon there with Princess Diana. Gibraltar is, at the moment, a 3 square mile piece of independent territory in southern Spain overlooking Morocco with some 30,000 inhabitants.
The original settlers came from around the Mediterranean: from Malta and Italy. Both Spanish and English is spoken in Gibraltar and most of the population are, unlike Britain, Catholics. Back in the 18th century, Spain ceded Gibraltar to Britain. Spain now wants Gibraltar back! In 1969, the people of Gibraltar included a proviso in its constitution that Gibraltar will only be returned to Spain if is population vote for this in a national referendum.
The Gibraltarians feel very passionate about not becoming part of Spain and Spain has been practicing all manner of restrictive practices towards Gibraltar, including causing a 3 hour wait to make a 100m drive across the border, even bribing ferry companies to move a few miles across into Spain to provide services to Tunis.
One has to consider the irony of this latest Anglo-Spanish diplomatic scuffle; true, Gibraltar with its geographical position almost at the mouth of the Med is well strategically placed, but equally, let's not forget that Spain maintains two separate territories in Morocco, which, strangely, Morocco wants back.
