Speaker John Bercow has ordered the suspension of more than 80 House of Commons passes amid concerns over lobbying, according to Sky News.
The passes were reportedly issued to all-party parliamentary groups (APPGs) of the kind allegedly set up by Tory MP Patrick Mercer after he was contacted by undercover reporters claiming to represent lobbyists seeking to lift Fiji's suspension from the Commonwealth.
A spokesman confirmed the issue was discussed at a meeting of the House of Commons Commission - a committee of senior MPs responsible for the administration of the Commons - but declined to disclose details.
"The commission at its regular meeting tonight discussed the issue of APPGs and will make a statement tomorrow," the spokesman said.
The Government will bring forward a bill to introduce a statutory register of lobbyists before Parliament's summer recess in July.
The hastily announced Government bill to create a statutory register of lobbyists is a highly politicised piece of legislation.
