Mr Martin, who campaigned passionately for Brexit, insisted it was time the bloc stood up to Jean-Claude Juncker and other EU leaders.
Speaking to Express.co.uk, the Wetherpoon boss said the only way for the European Union to avoid breaking up was to stand up to the President of the European Commission.
He said: “I don’t know if the EU will break up, but I think it will have to become even more autocratic to survive.
“They haven’t got a proper government, and you need a government to run the Euro.
Tim Martin blasted Jean-Claude Juncker in a furious tirade
“The government and the Euro are two sides of the same coin. So it will either break up or become even more autocratic, and I think the key thing is to go back to the basics.
“Reinstate a common market, and stop the power grab by Juncker and his cronies.”
The blast from the Wetherspoon boss comes as EU members attempt to strengthen Donald Tusk’s Brexit negotiation stance.
Some members remain insistent on the Brexit divorce bill being agreed before the UK can discuss a future trade deal with the European Union.
The Wetherspoon founder and chairman, who printed hundreds of thousands of pro-Brexit beer mats during last year’s campaign, rejected the idea that Britain needs to fight for a good deal.

Mr Martin said Britain must be prepared to walk away and rely on World Trade Organisation tariffs to ensure the UK has the best stance.
He said: “I think it will pan out well, providing that the Government doesn't think that everything depends on the trading agreement with the EU.
“The more the Government wants to do a trading agreement with the EU, the more vulnerable they are to blackmail and reaching bad deals.
“I think they have got to be perfectly happy using World Trading Organisation rules, and ignore the sirens of doom.”

Mr Martin continued his assault on the President of the European Commission as he highlighted the lack of democracy in the bloc.
He said: “It is very important to have a good relationship with EU citizens and their governments.
“I’m worried that the EU is a runaway train and it’s started making its own laws, it’s not properly democratic, President Juncker has never been elected, the court is not subjected to democratic controls.
“MEPs can’t even initiate legislation, they have got terrible problems of an increasing lack of democracy that they have to deal with.
“I hope France and Germany restrict Juncker’s power and eventually reclaim their own democracies.”
