"I will be positioned in the same seat by 2027," Starmer stated, joking that if the conversation was successful, he might invite the interviewer into Downing Street for a follow-up chat in the coming year.
There is never truly break for those in the top job. In the hour before our chat started, the PM had been speaking with Ukraine's Volodymyr Zelensky and attempting to decipher precisely had transpired in Venezuela, where his close political chum, US President Donald Trump, had recently launched a strike against and detained its leader, Nicolás Maduro.
When our lengthy talk, which was much longer than normal, had concluded, Maduro had been charged in New York.
As the new year begins, Sir Keir appears to have had something of a revitalisation. Maybe even just some relaxation with loved ones at Chequers, the prime minister's country retreat.
That certainly seemed to have left him in better spirits than at the sluggish end of 2025, a awful annus horribilis for him.
Yet, are he and his colleagues being unrealistic if they believe his standing are set to get better?
The harsh reality for the PM is that many of his fellow MPs think he's not very good at his job. A faction of them would sooner gamble and get him out in 2026.
But Starmer was rejecting the idea in the interview on Saturday morning.
On several occasions he insisted he'd be "evaluated at the next election", arguing nobody would remove his term from him – even if the most effective strategy of stopping Nigel Farage and Reform UK reaching No 10 could be for Labour to replace leader.
"We are in the battle of our generation and I intend to lead us," he said.
The problem for the PM is that he will be judged long before then – in a major set of elections in May throughout the UK. He tried to argue, maybe excessively, that they are concerning who runs local authorities, and who runs the devolved administrations in Holyrood or Cardiff – and not about Westminster.
True – up to a point. But even though he may be reluctant to admit it, No 10 will be held accountable by those elections too.
This did not stop Sir Keir suggesting that there were no circumstances under which he would step down, even if one of his colleagues contested his leadership for the job, if those elections prove catastrophic for Labour.
He tried to account for his low poll ratings by saying the public was reasonably impatient for things to get better. He tried to assure the interviewer, and the public, that this year would be a change.
The economic situation would improve in the face of rising unemployment, he claimed, when strategies the government put in place during their initial turbulent year began to show results.
His core message is that in 2026 the country will "reach a turning point".
The prime minister may have communicated with greater vigour than I've seen from him for a while – more relaxed, perhaps, with more time to talk.
However, in spite of encountering calls from within his own party for a bolder approach, with greater political clarity, more dynamism, more speed and more immediacy, his arguments were repeated ones.
Given that he is in considerable political difficulty, is a different approach required a new narrative?
No administration, and especially not one that has been struggling in the polls for an extended period, gets everything its own way.
Sir Keir's challenges are not only because governing is challenging, but because he and his team have made mistakes, including in the last few weeks.
The PM expressed regret that he was sorry for saying he was "pleased" to welcome back the Egyptian-British activist Alaa Abd El Fattah to the UK following an backlash when statements he'd previously made – such as calls for Zionists and police to be killed – resurfaced.
Starmer attributed it to "the system" for not realising what the activist had said before – a more diplomatic way of saying it wasn't his responsibility.
And he is inviting obvious political risks as the year progresses. His close relationship with the US president entails a new risk after Trump's strikes on Venezuela.
Having interviewed Sir Keir Starmer, a ex- human rights lawyer who opposed the war in Iraq, over his career, the notion he would be content with these events seems unlikely.
He stated he was a "career-long proponent of international law" but we "simply haven't got the full picture at the moment".
Some demanded criticise the action before the interview. And the government is expected to face further scrutiny to give an clear view in Parliament in the near future.
There has also always been simmering pressure in the Labour ranks to undo or remake some of the outcomes of Brexit.
The PM disputes he's pursuing that, but his new specific pledge to integrate further with the European trading bloc – the huge economic European market – will probably elicit protests that he is breaking his pledge never to try to reverse the results that flowed from Brexit.
A commitment to align with more of the single market will delight a faction on his side of the party, but it is prime ammunition for Reform and the Conservatives to
