Four of British Prime Minister David Cameron's main political opponents enjoy greater public trust than he does on the question of European Union membership, according to an opinion poll published Wednesday.
Just 18 per cent of respondents in the YouGov poll for The Times newspaper said they trust Cameron, who is campaigning for Britain to vote to remain in the EU ahead of an in-out referendum on June 23.
Fellow Conservative Boris Johnson, who is spearheading the Vote Leave campaign, is the most trusted, with 31 per cent backing him. He is followed by opposition Labour leader Jeremy Corbyn on 28 per cent.
Iain Duncan Smith, another Conservative rebel lobbying for Vote Leave, comes third with 25 per cent trusting him on the EU, while 22 per cent said they trust UK Independence Party leader Nigel Farage.
Corbyn wants Britain to remain in the EU, while anti-EU campaigner Farage leads a separate drive for it to leave.
The newspaper said the "so-called Project Fear, the series of outlandish claims used by Mr Cameron to try to win the referendum for Remain, is making him increasingly unpopular."
It was referring to a series of warnings from Cameron about the potential impact of a British EU exit, or Brexit, on the country's economy and security.
Cameron warned consumers on Tuesday that the average price of a family holiday in Europe could rise by 230 pounds (336 dollars) after a Brexit, prompting Vote Leave to accuse him of "talking down our country and our economy day after day" during his campaign.
In better news for Cameron, the YouGov poll found 44 per cent of people planned to vote to remain in the EU, 40 per cent said they would vote to leave, 12 per cent said they did not know how they would vote, and 3 per cent said they would not vote.
Cameron is marginally more trusted than Home Secretary Theresa May, who supports his Remain campaign, on 17 per cent. Justice Secretary Michael Gove, another prominent Vote Leave supporter, is trusted on the EU by just 16 per cent of people, the poll found.
