Ministers may have to reveal what guidance civil servants issued about Evgeny Lebedev before Boris Johnson appointed the Russian oligarch's son to the House of Lords.
Labour will force a binding vote on the release of information given to Boris Johnson before Lord Lebedev was made a peer, following reports the Prime Minister overruled concerns raised by MI5 and MI6.
Using a parliamentary mechanism called a Humble Address, Angela Rayner will call on Cabinet Office minister Steve Barclay to make public the details concerning the appointment. The Cabinet Office plays a central role in the vetting process of Lords.
