Sir Keir Starmer faced Kemi Badenoch at the despatch box on Wednesday for his final Prime Minister's Questions, with the Speaker opening proceedings by thanking the outgoing prime minister BBC. The session, at the customary noon slot, was flagged in advance by the Hansard Society's Parliament Matters bulletin as Sir Keir's last appearance at the despatch box in that capacity Hansard Society.

Sir Keir is due to step down as Labour leader on Friday, handing over to Andy Burnham, the MP for Makerfield BBC. The transition brings to an end a premiership that began after the 2024 general election, and it will be the first change of Labour leadership conducted from inside Downing Street since the party returned to office. Before facing his final PMQs, Sir Keir chaired his last Cabinet meeting in Downing Street, according to Sky News reporting.

Wednesday's exchange with Mrs Badenoch, the Leader of the Opposition, followed the format familiar to any Westminster watcher: six questions from the Leader of the Opposition, interspersed with backbench contributions and questions from other party leaders, including typically the leader of the SNP given the size of that party's Commons representation. The BBC's video output tagged the segment under Prime Minister's Questions, Keir Starmer, the Labour Party and the House of Commons, underlining the institutional rather than personal framing the corporation applied to the coverage BBC.

The Commons chamber had, a day earlier, held a rather different kind of business. On Monday 13 July MPs paid tribute to Ann Widdecombe, the former Conservative minister, following her death. The Hansard record of that debate noted she had served as Minister for Employment and, more prominently in public memory, as Minister for Prisons Hansard. Tributes of this kind are a well-worn convention at Westminster, suspending the ordinary cut-and-thrust of debate to allow MPs across parties to record their regard for a departed colleague, and they typically precede rather than follow the week's more contested business.

As of the current date, the official Hansard transcript for Wednesday 15 July had not yet been published, though the record for Tuesday 14 July was already available — a routine lag reflecting the time needed to prepare the official report rather than anything unusual about the sitting itself Hansard.

The week's Commons agenda was not confined to the change of prime minister. MPs were also scheduled to debate the Government's Immigration and Asylum Bill during the sitting week of 13–17 July, continuing its passage through the House Hansard Society. That legislation, one of the more contested items on the Government's programme, proceeds regardless of the change of leadership at Number 10 — a reminder that the machinery of government and the parliamentary timetable do not pause for a leadership transition, even one as consequential as this.

The mechanics of the handover are, on paper, straightforward. Sir Keir remains prime minister until he formally tenders his resignation to the King, at which point Mr Burnham — assuming he has by then completed the internal party process to become Labour leader — would be invited to form a government. The timing set out by the BBC has Sir Keir's departure as Labour leader falling on the Friday immediately after his final PMQs, with the practical transfer of the premiership expected to follow in short order.

For a governing party, the sight of a serving prime minister's last outing at the despatch box, followed within days by a new leader, is not without precedent in British politics, though mid-term changes of this kind always carry their own particular texture: the outgoing prime minister facing questions as a lame duck, the Leader of the Opposition calibrating tone between courtesy and challenge, and backbenchers on the government side already looking ahead to their new leader's priorities. Wednesday's session offered little sign of departure from that pattern, with the Speaker's opening thanks to Sir Keir the only formal acknowledgement, on camera, that this was a PMQs unlike any other this parliament.

What happens next in the Labour leadership process — and how quickly Mr Burnham moves from leader-designate to prime minister — will determine the precise shape of the handover in the days ahead. The Immigration and Asylum Bill's progress through the Commons this week will also be a first indicator of how much continuity the incoming leadership intends on the Government's existing legislative programme, though that is a matter for the coming weeks rather than for Wednesday's proceedings.
