The End of Starmer – The Mandelson Edition

  • It had to come. At some stage a decision would be taken that was the prime minister’s alone.
    • To govern is to choose, and Keir Starmer chose, perhaps even against his own instincts, Peter Mandelson. 
  • This is a moment of extreme jeopardy for Starmer. His personal judgement is now in question.
    • Winter fuel payments, free clothes, farmers’ tax, business rates, digital ID – none of these hinged on the judgement of Starmer alone. 
    • But he did choose to appoint Mandelson as Ambassador to the US – and to do so ahead of the completion of security vetting.
    • And, as Starmer made clear in Prime Minister’s Questions today, he did so knowing of Mandelson’s ongoing relationship with Epstein.
    • But he blames Mandelson for lying about the nature and depth of that relationship.
  • The criminal investigation has raised the stakes.
    • The police have asked No10 not to release documents that could prejudice their investigation, depriving the PM from immediately being able to prosecute his case. 
    • With every comment, text and communication potentially ending up in court, anyone implicated cannot spin their way out of it.  
  • The toxicity of Mandelson has dramatically shifted the balance of power in the Labour Party.
    • A whole generation of MPs have realised they not only backed the wrong horse, they backed the snake who could bring them all down.
      • Streeting, closely linked to Mandelson, has gone from heir apparent to crestfallen Icarus. 
  • Starmer has lost control of his majority.
    • He already knew he could not whip his MPs against the Conservatives’ humble address, designed to force all Mandelson-linked communications out into the open. But he amended the motion such that it would not provide “papers prejudicial to UK national security or international relations”.
    • He failed to realise that his own MPs have so little trust in him that they wouldn’t even pass this amendment, fearful of what Kemi Badenoch described as it becoming a whitewash exercise.
    • Angela Rayner and Meg Hillier came to the rescue by amending the amendment so that Parliament’s Intelligence and Security Committee (ISC) would play a role in judging the relevance of sensitive information (although it’s still not exactly clear how this will work in practice).     
  • Starmer has no way out.
    • His own MPs have lost trust in him.
      • The backbench Matt Bishop, a new MP with a majority of only 278 votes, gave a powerful speech where he said “How can I vote for an amendment that has the potential to conceal the behaviour of powerful people? What would I say to victims? That transparency matters, except when inconvenient. That accountability applies, except when it’s uncomfortable“.
      • Although the amended amendment ultimately passed, this sentiment is rife.
        • On our database of MPs, Matt Bishop had a neutral rating towards Keir Starmer. Once the PM loses those MPs in the middle, he has lost the support of his parliamentary party. 
  • His MPs have also lost trust in his chief of staff.
    • McSweeney is in the firing line from those who blame him for advocating for Mandelson, whom he has long been close to.
      • But the end of McSweeney ultimately means the end of Starmer.
  • And Starmer’s actions do not suggest trust can be restored.
    • The amendment passed because of the intervention from Rayner and Hillier.
    • His defence that he was misled by Mandelson leaves him looking weak. Leaders can’t be victims.
  • The public are watching.
    • According to YouGov, 95% say they are aware of the Mandelson story, including 44% who are watching it very or fairly closely.
  • And voters can see a PM who blocked a popular locally elected politician (Burnham) whilst installing without proper vetting a political insider renowned for dodgy dealings (Mandelson).
    • The voters of Gorton & Denton now have the chance in the 26 February by-election to show just how much they reject all the old parties and rush into the embrace of the insurgent Greens and Reform.
  • A popular highly-skilled politician might be able to find a way through. One who has plummeted in the polls cannot.
    • Boris Johnson was felled by the shenanigans of Chris Pincher and Owen Patterson, along with the loss of his chief of staff.
  • This is an existential moment for the Labour Party.
    • They know Starmer is an irrecoverable liability rather than a salvageable asset.
  • We said on 4 January that “The Labour Party might have little experience of changing the prime minister but events will force their hand.
    • Those events are now upon us. Starmer cannot escape.
