European leaders are walking on eggshells over the future of Gibraltar after Brexit.

EU leaders are due to sign off an agreement this weekend, on future relations between the UK and EU for decades to come.

Theresa May won't sign an agreement that affects its control of the disputed territory of Gibraltar.

The Sun's Nick Gutteridge told Mike Hosking the Spanish prime minister can't accept a deal, that keeps Gibraltar permanently under British control.

"The Spanish Prime Minister has to come away with something to show he has got his way, but how he is going to do that we just don't know."
