A Humble Address: How MPs confronted the Mandelson scandal - Parliament Matters podcast, Episode 130
6 Feb 2026
It has been a bruising week for the Prime Minister after the House of Commons backed a Conservative “Humble Address” demanding documents on Sir Keir Starmer’s vetting of Lord Mandelson for the Washington Ambassadorship. We explain how the procedure works, what role the Intelligence and Security Committee may play in decisions on disclosure, and how legislation to strip a peerage could be introduced. Plus, the latest on the Restoration and Renewal of Parliament as yet another report lands with a new set of costings.

The humble address – a procedural device revived by Sir Keir Starmer himself during the Brexit years – operates like a “parliamentary can-opener”, and in this case sharply intensified the pressure on the Prime Minister as Labour MPs signalled support for the Conservative Party's motion.
We unpack the debate’s twists and turns, including a manuscript amendment that called for Parliament’s Intelligence and Security Committee to be involved in assessing the Government’s proposed national security redactions after MPs warned the government’s original plan of leaving it to the Cabinet Secretary looked like “marking your own homework”.
We explain how the Intelligence and Security Committee says the disclosure process should work. We also examine how police interest may complicate publication and ask whether the “traitorous” language used in the Commons about Lord Mandelson could have consequences if any criminal proceedings follow. Then we examine the thorny constitutional problem of revoking a peerage, contrast it with removal from the Privy Council, and consider whether legislation could open the door to future political misuse.
Finally, we turn to the latest Restoration and Renewal report on the crumbling Palace of Westminster – yet another “Groundhog Day” moment – setting out the familiar conclusion that full decant remains the fastest, safest, and most cost-effective option, and discuss why the politicians will hesitate over the eye-watering numbers and the politics of moving out.

Ruth Fox: Welcome to Parliament Matters, the podcast about the institution at the heart of our democracy, Parliament itself. I'm Ruth Fox.
Mark D'Arcy: And I'm Mark D'Arcy. And coming up this week.
Ruth Fox: Power, plutocracy, pimping and peerages.
Mark D'Arcy: Should there be a way to defrock errant peers?
Ruth Fox: And groundhog day in the ongoing saga of how and when to save Parliament's crumbling buildings.
Mark D'Arcy: And Ruth, what a week it's been. This has been the week so far of Peter Mandelson in Parliament, and not in a good way. Peter Mandelson, the twice resigned cabinet minister, forced to resign again as [00:01:00] Britain's Ambassador to Washington. Let me correct myself. He didn't resign for the third time. He was in fact sacked, but there's three top level jobs that he's lost during his long career.
Peter Mandelson has been causing all sorts of difficulties for Sir Keir Starmer's government. Should they have appointed someone who turned out to have close links to the paedophile and financier, Jeffrey Epstein. Should he have been more closely scrutinised? Should he not have been given the job at all? What did Sir Keir Starmer know about his relationship with Epstein and when did he know it? Full transcript →
