<s>[INST] The next text is a question of a member of the European parliament:"On 29March2017, the European Council received a notification from the United Kingdom of its intention to leave the European Union and Euratom, as provided for by Article50 TEU.  On 29April2017, the European Council adopted the guidelines for the negotiations under Article50 TEU, which also indicated the positions and general principles that the Union would espouse during the negotiations.  Point 24 of the Council decision stipulated that:  ‘After the United Kingdom leaves the Union, no agreement between theEU and the United Kingdom may apply to the territory of Gibraltar without the agreement between the Kingdom of Spain and the United Kingdom’.  Within theEU, all Member States have equal status, and any differences require a specific legal basis in the Treaties.  What is the legal basis on which Point 24 above grants Spain a special right of ‘veto’ or at least a differentiated right in comparison with all the other EU Member States?"
