LONDON (AFP) -- Sir Ian Blair, Britain's top police officer, was under more pressure Saturday to resign over the fatal 2005 shooting of a Brazilian man mistaken for a suicide bomber.

Jean Charles de Menezes, 27, was shot seven times in the head at a London Underground train station on July 22, 2005, with the city still reeling from attacks on the public transport system two weeks before which killed 52 people.
London's Metropolitan Police force was found guilty on Thursday of breaching health and safety laws, though no individual was blamed for the killing.
Met Commissioner Blair has the backing of Prime Minister Gordon Brown, Home Secretary Jacqui Smith and London Mayor Ken Livingstone. The two main opposition parties are calling for his resignation.
Mohammed Abdul Kahar, 23, who was shot in the shoulder during a raid by police in Forest Gate, east London, said he and his brother Abul Koyair, 20, were stopped and surrounded by armed police, with one officer shouting ""Shoot him! Shoot him!"" The Times and The Guardian newspapers reported.
The brothers claim they were racially taunted.
The alleged incident occurred at the end of August this year and the brothers' lawyer has written to Blair to complain about the ""appalling situation that confronts the family again.""
Gareth Peirce said in the light of the police's ""strange"" claim that the De Menezes shooting was a unique incident, the brothers felt they had to speak out.
Independent witnesses saw the incident, Peirce said.
The Times said a vote of no confidence in Blair had been called for at the Metropolitan Police Authority, where up to half of the 23 members are expected to vote against him or abstain.
The MPA oversees the day-to-day running of the force and has the power to fire Blair.
Blair is first due to appear before the London Assembly on Wednesday.
Meanwhile The Guardian said it had learned that Blair would be criticized for his actions in the De Menezes affair in an official report to be released next week.
He would be criticized for what the daily said was attempting to block the Independent Police Complaints Commission from trying to investigate the shooting.
The IPCC investigates all fatalities either directly or indirectly involving British police.
The shooting of De Menezes came the day after another attempted attack was foiled. Police believed the Brazilian electrician was Hussain Osman, one of the plotters in that case, who was jailed for life earlier this year.
After a jury at London's Central Criminal Court returned its verdict, judge Richard Henriques fined the force 175,000 pounds (252,000 euros, 364,000 dollars) and ordered it to pay costs of 385,000 pounds.
""Responsibility must lie with Sir Ian Blair,"" said the Financial Times newspaper on Saturday.
""Sir Ian is a thoughtful man but he appears to learn slowly.
""He wants 'time to consider whether and how any of our current operating practices need to be altered in the light of this conviction.' That is a job better left to his successor. He should go.""
The Daily Mail's editorial asked: ""Why IS Sir Ian still in charge?""
