IVPN rebuts that argument at some length:

> What is the relationship between Gibraltar and UK?

> The main relationship between Gibraltar and UK stems from the fact that the British monarch is the head of state of both Gibraltar and UK. However, such a relationship is not enough to make Gibraltar a part of UK. For example, no one argues that Andorra is a part of France although the President of France is the head of Andorra (together with the Spanish/Roman Catholic Bishop of Urgell).
