Unlike most other British territories, Gibraltar has not been offered independence by the UK. It has been suggested that this is on the grounds that the Treaty of Utrecht, under which Spain ceded the territory to the British Crown, states that, if the British Crown should ever wish to dispose of Gibraltar, it must first be offered to Spain. However, the Government of Gibraltar has pointed out at the UN that Article 103 of the UN Charter overrules and annuls this "reversionary clause".
