Andy Burnham arrived at the Labour Party’s helm with a sweeping declaration: his victory, he told members on Friday, amounted to the biggest political change of the last 40 years.
In a country that has endured upheavals of every stripe over that same period, it was a striking claim from the man due to walk into Downing Street today as Britain’s new prime minister.
It also sets a demanding standard — because he will be judged not simply on whether he delivers, but on how quickly he does it.
Mr Burnham inherits a Number 10 that, to many in Westminster, has come to symbolise churn. The jokes now are that a revolving door might suit the famous black entrance better than a fixed one, given how often prime ministers have been replaced in recent years.
As he takes office, plenty will point out that he joins a long list of leaders who arrived promising to be the solution to the UK’s most stubborn problems.
From the cost-of-living crisis to defence spending, decisions awaiting the new prime minister will demand attention from his first hours in the job.

Yet the way the new Labour leader has reached Downing Street has left unusual gaps — and unanswered questions — about what comes next.
His leadership bid was, in effect, fought within a single constituency, focusing on issues most relevant to those voters rather than setting out a programme aimed at the whole country.
And because he faced no challenger for the leadership after becoming an MP last month, Mr Burnham never had the kind of contest that forces a candidate to spell out priorities, trade-offs and red lines.
He is also taking power without the traditional runway of opposition, when a shadow cabinet would typically already be assembled. While the pool for senior roles includes figures who have held office over the past two years, there is an expectation he will also elevate new faces into new posts.
All of that ensures his opening days will be watched even more closely than usual.
Supporters insist Andy Burnham has a plan, and argue that the mechanics of transition mean the details will be ready to deploy on day one of his premiership.

“Just wait, you’ll see,” is how allies put it.
But the recent warning from British politics is clear: one of the reasons Keir Starmer’s standing with voters collapsed was a sense among the electorate that they had already waited long enough for tangible results.
That is why the address Mr Burnham delivers outside Downing Street on his first day as prime minister is expected to carry particular weight for those seeking clarity.
He has spoken of changing politics and improving people’s lives; the pressing demand now is for specifics on how his version of Britain will be achieved — and, crucially, how it will be paid for.
One challenge for Mr Burnham is that the absence of a detailed blueprint has allowed expectations to grow in multiple directions, with party colleagues and voters alike imagining outcomes that match their own priorities.
Until now, Andy Burnham has functioned as something close to a blank canvas, onto which different groups could project their hopes for what the next chapter might bring.
That canvas will begin to fill as soon as he steps through the door of Number 10 — and it is inevitable that not everyone will like what appears.
And the past decade has shown, repeatedly, where that kind of disappointment can lead for those who have occupied the office before him.
