The UK's most senior civil servant, Sir Chris Wormald, has stepped down as Cabinet Secretary and Head of the Civil Service. This marks the shortest tenure for the position in its history, concluding just over a year after his appointment. The departure occurs amid a period of significant change within the Prime Minister's top team, following other recent high-profile exits.

The official statement from the government indicates that Sir Chris and the Prime Minister have agreed by mutual consent for him to step down. Sir Chris himself stated it was an "honour and a privilege" to serve for 35 years, particularly to lead the Service as Cabinet Secretary, and expressed his thanks to those he worked with.

Questions Surrounding Performance and Suitability

Conclusion and Next Steps
Sir Chris Wormald's departure as Cabinet Secretary concludes a period of significant change at the highest levels of the UK civil service. His tenure, now the shortest on record, raises questions about the factors contributing to this outcome. The immediate priority for the Prime Minister appears to be the appointment of a permanent successor, with Dame Antonia Romeo being widely cited as the leading candidate.
