A third post-mortem of Ian Tomlinson, the man who died after being pushed to the ground at G20 protests last year, has been withheld from the coroner.

The Crown Prosecution Service and Independent Police Complaints Commission are also understood not to have seen the examination, conducted by a forensic pathologist.

The post-mortem was carried out on behalf of the officer involved in the case. His lawyers have reportedly refused to release its results, citing legal privilege.

The results could now be the subject of a legal wrangle as coroner Paul Matthews is believed to be demanding a copy is made available to his inquest.

Video footage of the G20 protests caught the moment when Mr Tomlinson, a passer-by at the demonstrations in the City of London, was pushed to the ground by a police officer.

Question-marks over what actually caused his death were raised when the pathologist who carried out the first post-mortem on him was found guilty of misconduct.

Freddy Patel’s work was central to the decision not to pursue charges against the police officer who hit Mr Tomlinson and threw him to the ground.

Two pathologists later concluded that Mr Tomlinson had died of internal bleeding as a result of blunt force trauma and cirrhosis of the liver, but the contradiction between their findings and those of Dr Patel meant there were no charges.
