Fifty-four per cent of respondents said they trust the BBC more than the Government over claims about Iraq and weapons of mass destruction. Just 21 per cent said they had greater faith in the Government.
The poll, commissioned by Weber Shandwick, also revealed that 51 per cent said they trusted TV and radio news less now than they did one year ago.
More than half of respondents said they were much more likely (28 per cent) or somewhat more likely (26 per cent) to believe the Beeb on the issue of WMD.
In a further boost to the BBC, respondents said they trust the organisation more than other news organisations.
Of TV broadcasters, 44 per cent trusted the BBC most, ITV News scored 24 per cent and Sky scored just 13 per cent.
The questions were devised by WS's research arm KRC and the poll was conducted by NOP last weekend among 1,000 respondents.
