Damian McBride has insisted he did not break the law while working as a Labour spin doctor and said he would be happy to speak to police if they decide to look into complaints from a Conservative MP.
Asked if he was concerned about possible prosecution, Mr McBride said:
I am sure that I wasn't committing any criminal offences. I wouldn't leak confidential documents and I would take pains to not do so.
I would be happy to talk to the police if they wanted an explanation.
