But just two days ago, when the full text of the Tax Agreement was announced it simply said that the agreement did not imply any modification of the respective positions of Spain or of the UK "with regard to sovereignty and jurisdiction in relation to Gibraltar."
In excluding 'control' presumably it meant that there could have been modifications as regards 'control' in relation to Gibraltar.In fact, Spain has been awarded much control in respect of many sensitive areas such as taxation, companies, beneficial ownerships, trusts, land registry etc, etc, etc.
So that the time-honoured phrase of 'sovereignty, jurisdiction and control' is no longer there.
