Voters have delivered a damning verdict on Tony Blair on the eve of his 10th anniversary as leader.

An ICM poll for the Guardian has found that only 37 per cent of the public believe that their prime minister is an honest man.

It also shows that public support for the Iraq war has plummeted since May, with over half the country believing the conflict was unjustified.

More than half the country believes Blair lied over Iraq and 52 per cent see him as arrogant.

Only 37 per cent say he understands normal people and 62 per cent say he is too presidential.

His only positive attributes are his experience and competency.

Howard's blues

However, the wider Labour Party is not suffering along with its leader.

If Blair stepped down and was replaced by Gordon Brown, Labour would achieve a 41 per cent share of the vote at the next general election.

And with Blair at the helm, Labour still has a five point lead in voting intentions, with the Tories flat-lining on 30 per cent.

The three per cent drop for the Conservatives from May is alarming news for the party at a point in the electoral cycle when it should be strongly challenging or leading the government.

Tory leader Michael Howard's own satisfaction rating has slipped eight percentage points.

Conservative MPs are bound to be concerned that they are slipping back into the sights of the Liberal Democrats, who have risen four per cent in the polls since May to 25 per cent.
