LONDON: Two-thirds of Britons believe Prime Minister Tony Blair bears a share of the responsibility for the suicide bombings in London, according to a poll published on Tuesday. The ICM poll for The Guardian newspaper asked people to what extent Blairs decision to join the invasion of Iraq was responsible for the July 7 bombings that killed 56 people. Thirty-three percent said the prime minister bore a lot of responsibility, 31 percent thought he had a little responsibility, and 28 percent thought he was blameless. ICM interviewed 1,005 adults by telephone between July 15 and 17. The poll had a margin of error of 3 percentage points. ap
