"I'll be positioned in this position by 2027," the Prime Minister stated, noting that if the discussion was successful, he might invite the interviewer into his official residence for a follow-up chat next year.
For a PM, there's never truly downtime for leaders. Just an hour before our chat started, Starmer had been speaking with Ukraine's Volodymyr Zelensky and working to decipher precisely had happened in Venezuela, where his big political chum, US President Donald Trump, had just targeted and seized its leader, Nicolás Maduro.
Once the discussion, which was much longer than usual, had ended, Maduro had been formally accused in New York.
As the year starts, the Prime Minister appears to have had something of a refresh. Perhaps even just some relaxation with his family at Chequers, the prime minister's rural getaway.
That certainly appeared to have resulted in a more positive mood than at the difficult tail end of 2025, a terrible annus horribilis for him.
Yet, are he and his colleagues being unrealistic if they think his political fate are set to improve?
The grisly truth for the leader is that a significant number of his fellow MPs believe he's underperforming at his job. A faction of them would rather gamble and remove him in 2026.
However Sir Keir was rejecting the idea when we spoke on Saturday morning.
Multiple times he stated he'd be "evaluated at the general election", arguing no one would take his electoral mandate from him – even if the most effective strategy of stopping Nigel Farage and Reform UK getting to No 10 might be for Labour to change its leader.
"We are in the fight of our times and I aim to guide the party," he affirmed.
The issue for the PM is that he will be assessed well ahead of then – in a major 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 devolved administrations in Holyrood or Cardiff – and unrelated to Westminster.
True – to some extent. But even though he may be reluctant to acknowledge it, No 10 will be judged by those elections too.
Despite this, Sir Keir implying that there were no scenario under which he would walk away, even if a his MPs contested his leadership for the job, if those elections prove very poor for Labour.
He sought to rationalise his unpopularity by saying the voters was understandably impatient for things to improve. He tried to assure the interviewer, and the nation, that this year would be a change.
The economy would recover in the face of rising unemployment, he said, when policies the government implemented during their first turbulent year began to bear fruit.
His core argument is that this year the country will "reach a turning point".
The prime minister may have communicated with renewed vitality than I've seen from him for a some time – less tense, maybe, with more time to talk.
However, in spite of facing pressure from various quarters for a bolder strategy, with much more political direction, more urgency, more speed and more urgency, his explanations were repeated ones.
Given that he is in considerable political trouble, is a different approach required a different script?
No administration, and especially not one that has been unpopular for an extended period, gets everything its as desired.
Sir Keir's problems are not just because government is challenging, but because he and his colleagues have erred, including in the recent past.
The PM told me 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 past remarks he'd previously made – such as calls for Zionists and police to be killed – came to light.
Sir Keir attributed it to "the system" for failing to identify what the activist had said before – a more diplomatic way of saying it wasn't his responsibility.
And he is courting clear political perils as the year gets going. His close relationship with the US president acquires a new jeopardy after Trump's intervention on Venezuela.
Based on years of interviewing Sir Keir Starmer, a former human rights lawyer who opposed the war in Iraq, over his career, the notion he would be comfortable with such action seems implausible.
He stated he was a "longtime proponent of international law" but we "just haven't got the full picture at the moment".
Some called for him to denounce it prior to the interview. And the government is expected to face more pressure to give an explicit view in Parliament in the near future.
There has also consistently been growing tension in the Labour party to undo or remake some of the consequences of Brexit.
The PM disputes he's pursuing that, but his new firmer pledge to move closer with the single market – the giant economic European market – will likely provoke accusations that he is reneging on his promise never to try to undo the decisions that flowed from Brexit.
A move to cosy up to more of the single market will satisfy many on his backbenches, but it is simple material for Reform and the Conservatives to
