Lord Bilimoria, founder and chairman of Cobra Beer, said the UK would lose out on trade because of Brexit.
But Christopher Nieper, managing director of womenswear manufacturer David Nieper, strongly disagreed and said the UK would be in a stronger position for better trade deals.
Speaking on the Today programme, on BBC Radio 4, Mr Nieper said Brexit would have no impact on consumers.
He added demand for British goods around the world was “very strong”.
He said: “We’re not throwing anything away. We’ve asked all our sales offices in Europe, will Brexit make any difference and unanimously they say ‘no’, it will make no difference at all.
“Consumers choose to buy what they choose to buy regardless of whether Britain is part of a political union.
“I can tell you that the demand for British goods is very, very strong, perhaps stronger than the Government realises.
“Perhaps stronger than the CBI and other reports actually report.”
Britain could become part of a trans-Atlantic trade alliance even more lucrative than the European Union if the UK is unable to strike a suitable Brexit deal.
Officials are reportedly working behind the scenes to look at joining the North American Free Trade Agreement (Nafta) – the largest free trade deal in the world.
The three-nation bloc, which includes the United States, Canada and Mexico, has a combined GDP of £17.2trillion, compared with the EU’s output of £15.7trillion.
And if the UK were to join, British businesses would have easy access to North American markets – similar to the current trade arrangement with the EU.
Nafta membership would also remove the need to negotiate complex and long-winded trade deals with each country.
And with Britain added into the group, Nafta would account for more than 30 per cent of the global economy.
This revelation, reported in The Telegraph, comes as Theresa May updated MPs on Monday on the “real and tangible” progress being made in the stalled Brexit progress.
