The outgoing leader will hold farewell talks with his senior ministers in Downing Street before taking his last Commons grilling.
Sir Keir Starmer will face his last Cabinet and Prime Minister’s Questions, while Andy Burnham nears the Labour leadership finish line as nominations close on Wednesday.
The outgoing leader will hold farewell talks with his senior ministers in Downing Street before taking his last Commons grilling at the despatch box at noon.
Meanwhile, Makerfield MP and prime minister-in-waiting Mr Burnham will edge closer to No 10 as nominations for the Labour leadership formally close on Wednesday.
The former Greater Manchester mayor’s premiership has already been cemented after he received the backing of 369 of the party’s 403 MPs, making it mathematically impossible for a rival to enter the contest.
Under Labour rules, candidates need the backing of 81 MPs to stand in a contest, meaning he is set for a coronation.
The outgoing Prime Minister, who will leave No 10 on Monday, told a reception attended by campaigners whose causes he had supported that they had “made me who I am”.
He is spending his final days in office highlighting what he sees as his legacy – support for Ukraine and championing domestic campaigns like the Hillsborough Law.
The Prime Minister said: “I leave on Monday. I leave with good grace, I leave very pleased with what we’ve been able to achieve in government in the two years that I’ve had the privilege of being prime minister.
“I’m pleased to have delivered on the promises that I made to many people in this garden, and I’ll make this last promise, which is I will stand with you and walk with you for as long as I’ve got breath in my body.”
In a sign of the closer relationship he has tried to forge with European neighbours, he also attended Bastille Day celebrations in Paris on Tuesday with Emmanuel Macron, who awarded him the Legion d’honneur in recognition of his work with France on European security.
Speaking to reporters outside the Commons later on Tuesday, his successor Mr Burnham said people’s cost of living was “the issue of our times” as he was quizzed on his plans for government.
“If we want to connect politics better with people, well, let’s deal with some of the pressures people are under in terms of the everyday cost of transport, the bills that they’re paying. I heard it so often on doorsteps in the campaign,” he said.
“You know, life has changed for people, and it’s not necessarily got better. And I think we just need to be relentlessly focused on that.
“I have talked about more public control of the basics, and then through that control, cutting the cost. I did that with buses in Greater Manchester, and I carry that same principle forward.
“To me, the cost of living and reducing it is everything, and I think we need to regain the confidence in the public that we’ve got a credible plan to do that and make life better.”
The former mayor nearly achieved a clean sweep of declared nominations, had it not been for backbencher Neil Coyle backing ex-minister Catherine West, who pulled back from mounting an unlikely leadership challenge against Sir Keir in May.
Bermondsey and Old Southwark MP Mr Coyle said he had done so because he always nominates a woman and chose a fellow London MP who had previously said she wanted a contest.
