Gibraltar’s chief minister Fabian Picardo says he isn't surprised the Spanish Government is raising issues at the last minute.
“The position taken by the Spanish Government today does little to build mutual confidence and trust going forward."
He said, " The language of vetos and exclusions should be the language of the past. It has no place in the modern Europe of today at a time when both the UK and Gibraltar are trying to build a new positive future relationship with the EU."
Spain's threat to scupper that deal coincides with the signing of another, the Armed Forces Gibraltar Act, underlining the security relationship between the British military and local police.
Armed Forces Minister Mark Lancaster says it re-affirms Britain's support for Gibraltar, the document was signed on board the Royal Navy destroyer HMS Diamond.
