Rudderless: Starmer Faces the PLP as a Scottish Rebellion Breaks Cover

The government is teetering—and whether the Prime Minister can survive the week is no longer a whisper in the tea rooms, but a live, urgent question in the corridors of power.

Today has been nothing short of extraordinary for Number 10, and the dust is far from settling. Westminster had barely had time to digest the departure of the Prime Minister’s Chief of Staff, Morgan McSweeney—following the fallout of the Mandelson row—when the news broke that Director of Communications Tim Allan was also heading for the exit.

For many in the party, these departures are more than just a staff reshuffle; they are a case study in a Prime Minister appearing rudderless, no longer in control of the narrative, his own operation or destiny.

But the most devastating blow came shortly after lunchtime. In a move that has fundamentally shifted the tectonic plates of the Labour movement, the leader of Scottish Labour, Anas Sarwar, has called on Keir Starmer to step down.

The context here is critical. Heading into the last general election, Sarwar was widely seen as the First Minister-in-waiting. It was a foregone conclusion for many that Labour would reclaim Holyrood in May 2026. That confidence has evaporated. The SNP, once on the defensive, are now increasingly certain they can secure a massive mandate for a record-breaking third consecutive decade of power.

It is this brutal political reality—the fear of a Scottish wipeout—that has prompted Sarwar to go public. His intervention is a reality Starmer cannot easily outrun. Even if he survives the immediate storm, the verdict of his Scottish leader will be a permanent shadow over his authority, especially if the Welsh Leader follows suit.

In an indicator of the gravity of the situation, the hours following Sarwar’s intervention saw a torrent of social media activity from the Cabinet. One by one, senior ministers have posted messages of support. Even the “performative” nature of these posts—from senior figures like Angela Rayner and Lucy Powell—highlights the fragility of the moment. In a stable government, a minister supporting the PM isn’t news; today, the fact it wasn’t a given made it a headline.

As this evening falls, Sir Keir has just left Downing Street on his way to address the Parliamentary Labour Party (PLP). He will walk into that room with his back further against the wall than at any point in his political career. The audience in front of him is no longer just sceptical; they are asking the two questions: Are you still the best person to lead us? And if you are not, who would be the best replacement?

Expect more developments today and over the coming days.
