Theresa May last night condemned the retired police officer who leaked the highly sensitive information that piled pressure on Damian Green.
Accepting Mr Green’s resignation, the PM said she ‘shared concerns’ at ex-Scotland Yard detective Neil Lewis’s disclosures.
The computer expert had given an interview accusing the de-facto deputy prime minister of browsing pornography online for hours.
His actions sparked a police review as Met Commissioner Cressida Dick made it clear the police duty of confidentiality was for life.
In her reply to Mr Green last night, Mrs May said: ‘I share the concerns, raised once again from across the political spectrum, at the comments made by a former officer involved in that case in recent weeks.

‘I am glad that the Commissioner of the Metropolitan Police has condemned that, made clear that police officers’ duty of confidentiality endures after they leave the force, and that the Metropolitan Police’s professional standards department are reviewing the comments which have been made.’
Police have been accused of a vendetta against Mr Green because of an ill-fated inquiry into Home Office leaks in 2008, which led to senior officer Bob Quick losing his job.
Mr Lewis, 48, is now at the centre of an anti-corruption inquiry and could yet face prosecution for going public with the personal information.
He was one of the 30 officers from the Met’s counter-terror command involved in the raid on Mr Green’s parliamentary office as part of a probe into leaks of Home Office material. It was led by Mr Quick, then Scotland Yard’s assistant commissioner.
Earlier this month Mr Lewis said that, during the raid, he seized and examined a laptop used by the then shadow minister.
He accused Mr Green of being responsible for ‘thousands’ of pornographic thumbnail images retained in its memory. Mr Lewis admitted he had gone public to support his former boss, Mr Quick.
It was the appearance last month of Mr Quick’s draft statement to the Leveson inquiry into Press standards that threw Mr Green into the spotlight.
Excerpts were quoted in a Sunday newspaper, but Mr Quick denied responsibility.
It said police had found porn on Mr Green’s computer during the raid and a police officer would have been sacked for having similar material.
Former top terrorism officer Mr Quick was accused of harbouring a grudge against Mr Green after the leaks inquiry left his career fatally wounded.

Within months he had quit after mistakenly letting slip details of a counter-terror operation outside Downing Street.
But it was Mr Lewis’s comments that attracted most criticism, after he revealed keeping a police notebook about the inquiry and a copy of the politician’s hard-drive. Chief officers, the police watchdog, legal experts and politicians slammed the gross breach of confidentiality, branding the officer a disgrace.
They warned of a ‘police state’ if officers were able to selectively make public highly sensitive information.
Mr Lewis remains under investigation for a raft of alleged offences, including data protection and computer misuse crimes, as well as theft.
He could also be subject to a misconduct inquiry but as a retired officer he could not be forced to attend any hearing so there would be no formal outcome. The Met said the review into the Green leaks was ongoing.
