The death of Dr David Kelly has hit the British Prime Minster, Mr Tony Blair's standing with Labour voters as well as the public as a whole.
In a survey two thirds of those questioned said they felt deceived over Iraq's weapons of mass destruction.
And even 62 per cent of those who voted for Mr Blair at the last election felt misled, according to the study for the Sunday Telegraph.
BBC reports that the dossier on Iraqi WMD, published last September, was "sexed-up" by No 10 sparked the furious row that ended in Dr David Kelly's death.
A clear majority, 61 per cent , said they believed the BBC claims. Just 23 per cent felt they were untrue. More than half, 56 per cent , of Labour voters backed the BBC.
The Prime Minister admitted trust was "an issue" following Dr Kelly's death in a televised media briefing before he went on holiday.
But 58 per cent said they now trust him less, including 52 per cent of Labour supporters.
Asked who bore most responsibility for the MoD scientist's death, 55 per cent of those polled blamed the Government, 43 per cent said Dr Kelly himself and 40 per cent accused the BBC.
More than a third, 38 per cent , said Dr Kelly acted improperly by secretly speaking to a journalist but 46 per cent disagreed.
Defence Secretary Mr Geoff Hoon, Dr Kelly's ultimate boss, has come out worst from the first two weeks of evidence at Lord Hutton's inquiry into his death.
More than half, 52 per cent , said he should resign, while 50 per cent said Mr Blair's media chief Mr Alastair Campbell, who is set to stand down after Lord Hutton reports, should go.
Only a third, 33 per cent , said Mr Blair should quit Downing Street over the affair.
However, a majority, 58 per cent , said no clear evidence of WMD would be found compared with 29 per cent who said they would.
