Britain has the strongest “economic steroid” of democracy over the EU, and this is the key to prosperity and freedom, the pub chain boss said in a bumper trading update.
And posturing by unelected representatives from the bloc is set to inflict more damage on the likes of Italy, Spain and Greece, than Britain.
The likes of Mr Juncker and Mr Barnier are simply encouraging importers such as Wetherspoon to switch away from its EU suppliers, Mr Martin warned.
And this is of huge damage to eurozone countries where unemployment is rife.
Mr Martin said many members of Britain’s establishment fails to understand that Britain has the upper hand in Brexit talks.
He said: “It is my view that the main risk from the current Brexit negotiations is not to Wetherspoon, but to our excellent EU suppliers – and to EU economies.
“As the public instinctively understands, but few academics, economists, boardrooms and City institutions grasp, democracy is the strongest economic steroid – hence the astonishing rise of countries like Japan, Singapore and South Korea, after its adoption.
“In the current negotiations, democratically-elected politicians from the UK are dealing with unelected oligarchs from the EU.
“Since the oligarchs are not subject to judgement at the ballot box, their approach is dictated by more sectarian factors – the interests and ideology of EU apparatchiks like them, rather than residents or businesses from EU countries.
“As a result of their current posturing and threats, EU negotiators are inevitably encouraging importers like Wetherspoon to look elsewhere for supplies.
“This process is unlikely to have adverse effects on the UK economy, as companies will be able to switch to suppliers representing the 93 per cent of the world’s population which is not in the EU, but this evolution will eventually be highly damaging to the economy of the EU. “
He added: “It is my view that Juncker, Barnier, Selmayr, Verhofstadt and others need to take a wise-up pill in order to avoid causing further economic damage to struggling economies like Greece, Portugal, Spain and Italy – where youth unemployment, in particular, is at epidemic levels.
“There seems to be little genuine appetite for a free-trade deal from the Brussels bureaucracy, so EU companies are, paradoxically, reliant on the goodwill of UK consumers, who are likely to prefer tariff-free goods in the future from non-EU countries, which are generally in favour of free trade, rather than deals with companies which are subject to the diktat of those who wish to punish the UK.”
The comments come as Wetherspoon’s like-for-like sales increased by 6.1 per cent.
