Wetherspoons boss, Tim Maritn, clashed with French vineyard owner, Gavin Quinney, on LBC radio.
The pair called into LBC radio to speak to host Nick Ferrari on what a no deal Brexit would mean for the UK.
Before long, a heated row erupted between Mr Martin and Quinney over future tariffs if the UK leaves the EU without a deal.
MPs will vote on the Brexit deal on the 15th January and expect to debate leaving with no deal on the 14th.
Martin said: “If we leave the EU, one of the advantages is that we can scrap tariffs.
“So, Gavin’s wine will continue to come into the country tariff-free, but the difference will be you’ll save 8 to 12p per bottle on wine from the rest of the world.
“But you save 17 percent on children’s clothes, you save x percent on bananas, so much on oranges and all the rest of it.”
Gavin replied: “Tim, you’re not selling children’s clothes and bananas in Wetherspoons, you’re selling wine.
“The most you’re going to reduce a bottle of Australian wine is 8p and if the EU finishes the negotiation with Australia and removes that tariff, 8p we’re talking about on a bottle of wine, compared with the UK duty from 1st February will be £2.23 – 28-times more.
“The UK collects 63 percent of all excise duty on wine in the EU. It’s massive, whereas the tariff is tiny.”
Mr Martin hit back: “Our business depends on how well off our customers are and how well the economy does. If you hone in on one bottle of wine, it’s a little bit dissective.
“We save £600 per person because that’s what the £39bn we’re supposed to pay to the EU is and there’s no legal liability for that.”
From what I can see, listeners are in agreement that Mr Martin is spot on with his claims.
