The whispers have turned into something louder now, and nobody in Westminster is pretending otherwise.
Just weeks ago, the conventional wisdom was that Keir Starmer would dig in, steady the ship, and fight the next election as Labour leader. That wisdom is looking shakier by the day. Andy Burnham’s commanding victory in the Leigh and Atherton by-election hasn’t just boosted the Greater Manchester mayor’s profile; it’s given his supporters exactly the ammunition they were waiting for.
The numbers are brutal for Starmer. Labour’s poll ratings have barely budged despite months of what Downing Street calls “tough decisions.” The party’s internal research, according to sources close to the leadership, shows voters in key English marginals simply aren’t warming to the prime minister personally. And in politics, that’s the kind of gap that doesn’t close easily.
Burnham, for his part, has been careful. He congratulated the government on its NHS investment announcements this week, praised the Budget’s housing commitments, and studiously avoided anything that could be called a leadership pitch. He doesn’t need to say a word. His allies are saying plenty.
“Andy’s shown he can win big in places Labour needs to hold. That matters more than any reshuffle.”
That line, from a senior Labour MP who asked not to be named, captures the mood in the parliamentary party right now. It’s not open revolt, not yet. But the loyalty that usually surrounds a sitting prime minister in his first term feels thinner than it should.
Starmer’s team insists he’s focused entirely on governing, not internal politics. And there’s something to that. He has a full parliamentary majority, a functioning cabinet, and time on his side if the economy cooperates. If inflation falls and growth picks up by 2026, this conversation looks very different.
But politics rarely waits for the economy to behave. The question now isn’t whether Burnham fancies his chances; it’s whether Starmer can give Labour MPs a compelling reason to stick with him before that question answers itself.
