Some 1,025 holidaymakers and 1,622 travel trade executives were surveyed.

Just six percent of people said they are more likely to book a trip across the Atlantic while President Trump is in office.

The slump is predicted to cause a £5.7 billion fall in tourism-generated revenue this year.

"There is now clear evidence that some people are being put off visiting the US," said one expert.

More than a quarter of British holidaymakers are put off visiting the US while Donald Trump is president, a survey has found.

Just six per cent of people said they are more likely to book a trip across the Atlantic while President Trump is leader.

The stats come despite Lonely Planet naming America’s Deep South and Alaska as two of its top 10 regions to visit in 2018.

The research also found that 40 per cent of travel trade executives disagree that America "is a country to do business with" while President Trump is in power.

The survey’s results were published to mark the opening of trade show World Travel Market (WTM) at the Excel exhibition centre in east London on Monday.

In January, just weeks after entering office, the billionaire businessman introduced a controversial executive order banning visitors from seven Muslim countries hours after Theresa May became the first foreign leader to meet him in the Oval Office.

The president said the measure - subsequently challenged in the courts - was necessary for security reasons.

Some 1,025 holidaymakers and 1,622 travel trade executives took part in the survey. Its results support previous evidence showing Mr Trump's election has had a negative impact on US inbound tourism.

Online travel firm Kayak reported a 30 per cent fall in searches for flights to the US when the result of the presidential election was confirmed in November last year.

The Global Business Travel Association has predicted that a drop-off in tourism will result in 4.3 million fewer visitors to the US this year, worth 7.4 billion US dollars (£5.7 billion) in lost revenue.

WTM London spokesman Paul Nelson said: "There is now clear evidence that some people are being put off visiting the US and some of travel's top executives are concerned about the Trump effect on their businesses.

"The US is one of the world's key destinations and has long been popular among Brits. It is important that America gets the message out that not only is it still open for visitors but that it continues to be a warm, welcoming and great value destination."
