Paul Quigley launched the scathing attack on the “foolhardy” Brussels club which is trying to “see what it can grab hold of before it goes down the tubes”.
His remarks come after it emerged EU President Donald Tusk handed Spain a say in the future of the Rock when Britain leaves the bloc, prompting concerns over the future of British expats living in Gibraltar.
However Mr Quigley reassured expats, saying the issue has “nothing to do with Spain” and “Gibraltar is and will stay as British as roast beef and yorkshire pudding”.

Mariano Rajoy is said to be keen for Spain to gain control of Gibraltar
The EU has such a pathetically weak hand it is panicking and desperately clawing around to see what it can grab hold of before it goes down the tubes
He told Express.co.uk: “The EU has no legal standing whatsoever in this matter. Since the Treaty of Utrecht in 1717, Gibraltar is a sovereign part of the United Kingdom of Great Britain and Northern Ireland.
“The EU has absolutely no jurisdiction over this. No attention or credibility need be given to such arrant nonsense coming from this unelected comissars in an undemocratic institution.”
He also accused Brussels of “sequestering” Spain’s former sovereign rights.
Mr Quigley said: “Spain is still part of the European Union, so this is a contradiction in terms, as the EU has effectively sequestered all of Spain's former sovereign rights anyway, so it would be an issue between the British Government and Brussels.
“This is nothing to do with Spain. So these EU clowns can't have it both ways.”

Spain has been emboldened in its position on the world stage after the EU published its Brexit negotiation guidelines.
After some last-minute talks from Prime Minister Mariano Rajoy, a text included a reference to the Rock.
Any post-Brexit agreement between the UK and the EU would not apply to Gibraltar “without the agreement between… Spain and the United Kingdom”, the statement said.
It indicated, at least in diplomatic terms, the EU was siding with Spain over the issue of the territory on The Rock.
But Mr Quiqley dismissed the row as “all smoke and mirrors”.
He told Express.co.uk: “The EU cannot actually punish UK whatsoever as Britain is not only the fifth largest economy in the world, but also in strategic terms, Gibraltar is a key British interest in global geo-politics.
“You don't mess around with military and security issues with Blighty.

“It's all smoke and mirrors as the EU has such a pathetically weak hand it is panicking and desperately clawing around to see what it can grab hold of before it goes down the tubes, as a failed political and economic union based on and undemocratic totalitarian dictatorship.
