"I will be sitting in the same position by 2027," the Prime Minister declared, joking that if our conversation went well, he might invite us into Downing Street for another talk in 2026.
There is rarely ever time off for those in the top job. Shortly before the interview began, the PM had been on the phone with Ukraine's Volodymyr Zelensky and trying to decipher what on earth had occurred in Venezuela, where his big political chum, US President Donald Trump, had recently launched a strike against and detained its leader, Nicolás Maduro.
By the time the discussion, which was much longer than usual, had concluded, Maduro had been charged in New York.
As the new year begins, Starmer seems to have had a degree of a reboot. Perhaps even just a bit of a rest with his family at Chequers, the prime minister's rural getaway.
That certainly seemed to have put him in better spirits than at the sluggish end of 2025, a terrible year politically for him.
But are he and his colleagues being unrealistic if they think his political fate are about to turn around?
The grisly truth for the leader is that numerous of his colleagues believe he's not very good at his job. Several of them would rather take a risk and oust him sooner rather than later.
But Starmer was dismissing such talk in the interview on Saturday morning.
Repeatedly he insisted he'd be "evaluated at the general election", arguing no one would remove his term from him – even if the most effective strategy of stopping Nigel Farage and Reform UK reaching No 10 might be for Labour to switch its leader.
"This is the struggle of our lifetime and I aim to lead us," he said.
The issue for the prime minister is that he will be scrutinised far sooner than then – in a huge set of elections in May throughout the UK. He sought to argue, perhaps too much, that they are concerning who runs councils, and who runs the governments in Holyrood or Cardiff – and unrelated to Westminster.
Accurate – to some extent. But even though he may not want to concede it, No 10 will be held accountable by those elections too.
Despite this, Sir Keir suggesting that there were no circumstances under which he would step down, should a his colleagues challenged him for the job, should those elections prove catastrophic for Labour.
He attempted to rationalise his low poll ratings by saying the electorate was reasonably eager for things to improve. He aimed to convince the interviewer, and the nation, that this year would be a change.
The economy would strengthen in the face of rising unemployment, he argued, when plans the administration implemented during their first rocky year began to bear fruit.
His core point is that soon the country will "see an improvement".
The prime minister may have spoken with greater vigour than observed from him for a while – calmer, perhaps, with more time to talk.
However, in spite of facing demands from within his own party for a bolder strategy, with increased political vision, more vigour, more speed and more immediacy, his arguments were familiar ones.
When he finds himself in such significant political peril, is a different approach required a new narrative?
No administration, and certainly not one that has been struggling in the polls for many months, has everything its as planned.
Sir Keir's problems are not only because government is hard, but because he and his colleagues have faltered, even in the last few weeks.
The prime minister admitted that he was sorry for saying he was "happy" to welcome back the Egyptian-British activist Alaa Abd El Fattah to the UK following an controversy when comments he'd previously made – including calls for Zionists and police to be killed – came to light.
Sir Keir blamed "procedures" for not catching what the activist had said before – a more diplomatic way of saying it wasn't his responsibility.
And he is inviting obvious political perils as the year gets going. His friendship with the US president acquires a new risk after Trump's military action on Venezuela.
Having interviewed Sir Keir Starmer, a ex- human rights lawyer who was against the war in Iraq, over many years, the thought he would be comfortable with such action seems implausible.
He stated he was a "career-long advocate of international law" but we "just lack the entire story at the moment".
Critics demanded condemn it prior to the interview. And the government is expected to face further scrutiny to give an definitive view in Parliament in the near future.
And there has long been growing tension in the Labour ranks to undo or remake some of the outcomes of Brexit.
The PM disputes he's pursuing that, but his new more concrete plan to move closer with the European trading bloc – the giant economic European trading zone – will likely trigger protests that he is reneging on his pledge never to try to overturn the choices that flowed from Brexit.
A commitment to cosy up to more of the single market will please a faction on his backbenches, but it is simple material for Reform and the Conservatives to
