Pressure on Speaker John Bercow over the bullying of Commons staff has intensified after three Tory MPs quit a committee he set up to improve “inclusion” at Westminster.

The Speaker’s Office said Will Quince, Mims Davies and Anne Milton had resigned from the Commons Reference Group on Representation and Inclusion, which is chaired by Mr Bercow.

In a statement, Mr Quince said he did not believe Mr Bercow was the right person to resolve the “numerous and serious issues” which had been raised about the conduct of some MPs and Commons staff.

The moves come after a damning report by Dame Laura Cox QC highlighted a Westminster culture which allowed the bullying and sexual harassment of staff to flourish.

The former High Court judge questioned whether the issue could be tackled successfully under the present Commons leadership – leading to calls for Mr Bercow to stand down.

Mr Quince said he was quitting the reference group “with regret” as he believed it had made good progress in creating a more inclusive environment.

“However, in the light of the Dame Laura Cox report, sadly I cannot in good conscience remain as a member of the group while John Bercow is chair,” he said.

“As much as I personally like John, I have reluctantly reached the conclusion that he is not the right person to resolve the numerous and serious issues.”

Ms Davies said: “I felt that remaining on this (committee) currently did not sit right following Dame Laura Cox’s report, and as this committee is chaired by the Speaker, I sadly felt in a difficult position. I did not take this decision lightly.”

In a statement, a spokeswoman for the Speaker’s Office said Mr Bercow had accepted their resignations “with regret” and paid tribute to them as “stellar members” of the group.

She said the Speaker would consider the group’s future after the House of Commons Commission has met on Wednesday to consider Dame Laura’s report.

“Dame Laura Cox’s report has highlighted some of the most significant challenges women face in our parliamentary culture,” the spokeswoman said.

“In the spirit of an independent approach, the Speaker feels it is right to reflect on the best means of tackling these cultural issues via the House’s response to the Cox report.

“He will therefore consider the future of the reference group following the commission meeting tomorrow.”

Dame Laura was appointed to head an investigation after BBC Two’s Newsnight highlighted claims of bullying of Commons staff by MPs and other staff, including Mr Bercow – allegations which he strongly denied.

Ahead of Wednesday’s meeting of the Commons Commission, Labour accepted the recommendations of the Cox report.

A party spokeswoman said: “The report highlights a culture and practices that are unacceptable in any workplace. It is vital that this is put right as a matter of urgency.”

The party called for changes to be made as quickly as possible to establish an independent process for complaints against MPs which does not involve fellow MPs deciding on cases, and to ensure the new Independent Complaints and Grievance Scheme should also be open to historical allegations.

Labour also called for a change in culture so that staff in the Commons have full confidence that any complaints they have will be taken seriously, as well as proper training for managers and full trade union recognition across Parliament.

“The Labour Party’s representatives on the House of Commons Commission will urge tomorrow that this approach and necessary changes are implemented as quickly as possible, working with trade unions and other stakeholders,” the party spokeswoman said.
