"I will be sitting in this office by 2027," Starmer declared, adding that if the discussion proceeded smoothly, he might invite the interviewer into his official residence for another talk in 2026.
There is rarely ever break for leaders. Just an hour before we sat down, Sir Keir had been speaking with Ukrainian President Volodymyr Zelensky and working to work out precisely had occurred in Venezuela, where his close friend, US President Donald Trump, had recently attacked and captured its leader, Nicolás Maduro.
By the time our lengthy talk, which was much longer than usual, had ended, Maduro had been indicted in New York.
As the year commences, Starmer appears to have had a kind of a revitalisation. Maybe even just a bit of a rest with the family at Chequers, the prime minister's country retreat.
That certainly appeared to have put him in better spirits than at the sluggish conclusion of 2025, a terrible year politically for him.
Yet, are he and his colleagues deluding themselves if they reckon his fortunes are poised to get better?
The harsh reality for the leader is that numerous of his fellow MPs are convinced he's underperforming at his job. Some of them would sooner take a risk and get him out this year.
However Sir Keir was having none of it in the interview on Saturday morning.
Multiple times he stated he'd be "assessed at the general election", maintaining nobody would take his term from him – despite the fact that the best chance of preventing Nigel Farage and Reform UK reaching No 10 could be for Labour to replace leader.
"This is the fight of our generation and I aim to be at the forefront," he said.
The challenge for the PM is that he will be scrutinised long before then – in a mega set of elections in May throughout the UK. He tried to protest, maybe excessively, that they are concerning who runs councils, and who runs the governments in Holyrood or Cardiff – and not a verdict on Westminster.
True – up to a point. But even though he may be reluctant to acknowledge it, No 10 will be judged by those elections too.
Despite this, Sir Keir stating that there were no scenario under which he would resign, should a his colleagues contested his leadership for the job, should those elections be disastrous for Labour.
He sought to rationalise his unpopularity by saying the public was naturally eager for things to change. He aimed to convince the interviewer, and the nation, that 2026 would be a change.
The economy would recover in the face of rising unemployment, he said, when policies the government enacted during their first turbulent year began to show results.
His core argument is that in 2026 the country will "reach a turning point".
The PM may have spoken with renewed vitality than I've seen from him for a some time – less tense, maybe, with more time to talk.
But despite facing calls from many directions for a more decisive strategy, with greater political direction, more urgency, more pace and more urgency, his arguments were well-known ones.
When he finds himself in this much political peril, does he need a change of tack?
No government, and especially not one that has been unpopular for an extended period, gets everything its as planned.
Sir Keir's challenges are not just because governing is difficult, but because he and his colleagues have erred, including in the last few weeks.
The prime minister expressed regret that he regretted saying he was "happy" to welcome back the Egyptian-British activist Alaa Abd El Fattah to the UK after an backlash when statements he'd previously made – such as calls for Zionists and police to be killed – surfaced.
Starmer blamed "procedures" for failing to identify what the activist had said before – a fancier way of saying it wasn't his responsibility.
And he is courting clear political risks as the year gets going. His close relationship with the US president takes on a new risk after Trump's intervention on Venezuela.
Having interviewed Sir Keir Starmer, a ex- human rights lawyer who opposed the war in Iraq, over many years, the notion he would be content with this kind of intervention seems unlikely.
He asserted he was a "lifelong champion of international law" but the public "just lack the full picture at the moment".
Some demanded denounce it before the interview. And the government is likely to face increased demands to give an explicit view in Parliament in the coming days.
And there has long been simmering pressure in the Labour party to undo or remake some of the consequences of Brexit.
Sir Keir denies he's doing that, but his new specific pledge to move closer with the European trading bloc – the giant economic European market – will likely elicit accusations that he is going back on his pledge never to try to reverse the results that stemmed from Brexit.
A decision to align with more of the single market will please some on his side of the party, but it is prime ammunition for Reform and the Conservatives to
