When Rishi Sunak was chancellor, Treasury aides and ministers said he was deeply entrenched in the detail, able to refer to spreadsheets or reports by chapter number by heart. The job of prime minister is a very different one, which his closest aides in No 10 say he is starting to understand means choosing very specific priorities.
Sunak has suggested to MPs who have seen him recently that he has three main priorities for his premiership: stabilising the economy, tackling small boat crossings in the Channel, and easing the pressures on the NHS.
