"I'll remain in this office by 2027," the Prime Minister declared, joking that if the discussion went well, he might invite us into Downing Street for a follow-up chat in 2026.
There is never truly downtime for leaders. Just an hour before we sat down, Starmer had been on the phone with Ukrainian President Volodymyr Zelensky and working to work out precisely had happened in Venezuela, where his close political chum, US President Donald Trump, had just launched a strike against and detained its leader, Nicolás Maduro.
When our interview, which was considerably lengthier than usual, had finished, Maduro had been indicted in New York.
But as the year commences, Starmer appears to have had a degree of a refresh. Maybe even just some downtime with his family at Chequers, the prime minister's rural getaway.
This appeared to have put him in improved morale than at the sluggish tail end of 2025, a awful annus horribilis for him.
But are he and his colleagues being unrealistic if they reckon his standing are poised to get better?
The harsh truth for the PM is that numerous of his party members are convinced he's ineffective at his job. A faction of them would sooner gamble and remove him this year.
But Sir Keir was rejecting the idea in the interview on Saturday morning.
Multiple times he stated he'd be "judged at the general election", maintaining nobody would take his electoral mandate from him – even if the best chance of preventing Nigel Farage and Reform UK entering No 10 may be for Labour to switch leader.
"This is the fight of our lifetime and I intend to guide the party," he declared.
The problem for the PM is that he will be judged far sooner than then – in a mega set of elections in May throughout the UK. He tried to protest, perhaps too much, that they are about who runs local authorities, and who runs the governments in Holyrood or Cardiff – and not a verdict on Westminster.
True – to some extent. But even though he may not want to concede it, No 10 will be held accountable by those elections too.
This did not stop Sir Keir implying that there were no situation under which he would step down, should one of his colleagues contested his leadership for the job, should those elections prove very poor for Labour.
He sought to rationalise his unpopularity by saying the public was understandably anxious for things to get better. He sought to assure me, and the nation, that the coming months would be a change.
The economy would recover despite rising unemployment, he said, when plans the administration implemented during their first choppy year began to take effect.
His core message is that this year the country will "see an improvement".
The prime minister may have spoken with renewed vitality than observed from him for a some time – calmer, perhaps, with a longer slot to talk.
But despite encountering pressure from within his own party for a more decisive strategy, with greater political direction, more vigour, more speed and more urgency, his arguments were repeated ones.
When he finds himself in this much political trouble, is a different approach required a new narrative?
No government, and certainly not one that has been unpopular for an extended period, has everything its as desired.
Sir Keir's problems are not just because government is challenging, but because he and his colleagues have made mistakes, including in the recent past.
The prime minister told me 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 – resurfaced.
Starmer attributed it to "procedures" for failing to identify 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 alliance with the US president takes on a new jeopardy after Trump's military action on Venezuela.
Having interviewed Sir Keir Starmer, a former human rights lawyer who opposed the war in Iraq, over a long period, the idea he would be at ease with these events seems unlikely.
He asserted he was a "lifelong advocate of international law" but the public "just do not have the entire story at the moment".
Opponents demanded criticise the action before we spoke. And the administration is likely to face more pressure to give an clear view in Parliament in the next few days.
And there has long been growing pressure in the Labour ranks to revisit some of the consequences of Brexit.
The PM rejects he's heading in that direction, but his new more concrete plan to integrate further with the European trading bloc – the giant economic European trading zone – will likely provoke protests that he is going back on his vow never to try to undo the choices that stemmed from Brexit.
A commitment to align with more of the single market will delight many on his own side, but it is prime ammunition for Reform and the Conservatives to
