Fabian Picardo, 45, also pledged to residents they would not become the “victims of Brexit,” in a rousing interview.
He added Gibraltar will “energetically and enthusiastically” work to deliver a successful Brexit,
Mr Picardo said Gibraltar had made its position clear as to what it needed from the Brexit negotiations and had received assurances from the UK Government that its interests would be looked after.
He said: “We were all in favour of remaining in the EU, 96 per cent of us voted to remain, but it’s our obligation to energetically and enthusiastically now pursue the result of the referendum and deliver a successful Brexit.

“We saw it in 1987 in relation to the exclusion of Gibraltar’s airport from the Open Skies agreements that were done in those days, air liberalisation as it was known.
“But I’ve had cast-iron assurances from David Davis, the secretary of state, I’ve no reason to doubt, he told me about not doing a trade deal if it didn’t include Gibraltar – if it was relevant to Gibraltar – will be the case going forward.
“This is a fluid moment, it’s a moment of aspiration when we try and do the best possible deal for the whole of the United Kingdom, including Gibraltar, and success will mean Gibraltar is included in those trade…
