Andy Burnham will become Prime Minister on Monday. That is now mathematically certain after he secured enough Labour leadership support to make a contested race impossible. Keir Starmer attended Bastille Day celebrations in Paris as one of his final acts on the international stage, receiving warm tributes from Macron, Zelenskyy, and Merz. The French president told Starmer "we owe you a lot, Prime Minister." The German chancellor said he would phone for advice. Zelenskyy thanked him for "constant, steadfast support." The Hillsborough law bill — officially the public office (accountability) bill — is expected to pass the Commons today after the government dropped provisions that would have given the security services an effective opt-out. The bill introduces a duty of candour for public officials. Burnham, who as culture secretary gave the pivotal speech at the 2009 Hillsborough memorial, frames the law as targeting what Bishop James Jones called "the patronising disposition of unaccountable power." Campaigners including Charlotte Hennessy, Sue Roberts, Steve Kelly, and Margaret Aspinall welcomed the concession, saying: "We have shown that true power belongs to ordinary people." Burnham's first fracture as incoming PM arrived before he even took office. He voted for the government's immigration and asylum bill last night, drawing criticism from his own flank. Fourteen Labour MPs voted against. Green candidate Geraldine Coggins, running in the byelection to replace Burnham as Greater Manchester mayor, called his vote "shameful" and an act of "performative cruelty," urging Labour's mayoral candidate Bev Craig to disown it. Rachel Reeves is delivering what is likely her final Mansion House speech as chancellor tonight, defending her economic record before an expected sacking or demotion under Burnham. She will claim Britain had the fastest G7 growth at the start of 2026, that borrowing fell from 5.2% to 4.3% — its lowest in six years — and that waiting lists are falling faster than at any point in 17 years. She will urge her successor to maintain the fiscal credibility she claims to have built. Ed Davey, the Lib Dem leader, is pressing Burnham to introduce proportional representation immediately rather than deferring it to the next manifesto. Burnham supports PR in principle but says Labour lacks a mandate since it was not in the party's election manifesto. Davey's challenge: "Be bold. Be brave. Fix the broken electoral system... And do it now. Don't wait until after the next election — when you might be powerless to do anything about it." The Hillsborough law is the most structurally significant development here. It names a real pattern — Hillsborough, infected blood, Grenfell, the Post Office — where institutions protected themselves at the expense of the public they serve. Whether a duty of candour actually dismantles that culture or merely adds a procedural layer depends entirely on enforcement mechanisms and whether future governments water it down in the Lords or through statutory instruments. The immigration vote reveals the tension that will define Burnham's premiership: a leader whose political identity was forged in community accountability politics, now voting for legislation his own allies call cruel. The question is whether Burnham's rhetoric about redistributing power and dismantling unaccountability will survive contact with the incentive structures of Downing Street.
