Theresa May’s closest ally and reportedly the most powerful man in the British government Damian Green — who attempted to castigate Breitbart London as “fake news” and blame it for political violence — may face a second sexual misconduct inquiry as victims are urged to come forward.

A new inquiry into sex abuse and extreme pornography violations is expected to take place under Kathryn Hudson, the parliamentary commissioner for standards, reports the Sunday Times which states her role is expected to be expanded this coming week.

The new responsibilities for the commissioner will come amid cross-party talks in Westminster in the wake of the recent sexual conduct scandal which has touched show business, politics, and a number of other industries.

Green is already being investigated by his own Cabinet Office, but this has been criticised as being insufficiently independent. The long-anticipated report on his behaviour has been delayed and is not now expected to be released until after Christmas.

While victims of Mr Green have been urged to come forward to the new investigation, the allegations he presently faces surrounds pornography found on his office computer, and sexual harassment.

In October, Green played to the gallery at a lunch for journalists where he said their competitors in the form of new media outlets were “fake news” which in his opinion endangered democracy and led to members of parliament being murdered.

Breitbart London reported in November the remarks of police sources in November who investigated Green’s laptop in 2009 during an investigation into government leaks. One said: “Porn was being accessed on an almost virtual daily basis. Police were told nothing could be done.

“Quite simply, it was not illegal to be in possession of extreme images before January 2009. If the raid had happened a few weeks later it would have been.”
