Two-thirds of Britons think the July 7 bombings in London were linked to Prime Minister Tony Blair's support for the US-led invasion of Iraq, according to a poll published on Tuesday.
The ICM survey for the Guardian newspaper found 33% of Britons believe Blair bears "a lot" of responsibility for the London bombings and a further 31% "a little".
Only 28% of those polled said Iraq and the London bombings were not connected.
Blair has rejected any link between Iraq and the blasts which killed 56 people and wounded hundreds more on three underground trains and a bus in central London.
He will use a meeting with Muslim leaders at his Downing Street office on Tuesday to blame extremists who have a "perverted view of Islam", his spokesman said on Monday.
Blair will say that these extremists will use any argument, from western colonialism to the Israeli/Palestinian conflict, to try to justify their violence.
His government on Monday rejected a thinktank report which said the invasion of Iraq had boosted recruitment and fundraising for al Qaeda, suspected of being behind the London bombings.
The Guardian poll found the attacks had had little effect on the popularity of Blair's ruling Labour Party, which won a third straight election on May 5.
The survey found Labour had stretched its lead over the main opposition Conservative Party by one point since last month.
Three-quarters of the 1,005 adults polled by ICM thought there would be more attacks in London. Despite this, eight out of 10 said they were no less likely to travel into central London.
