Who’s who in Westminster?
Following Andy Burnham’s appointment as Prime Minister, many of the key advisers from the Starmer Government have moved on. While some have remained in post or taken on new roles, a significant number of new faces are now shaping policy from behind the black door of No. 10 and across Whitehall.
The structure of No. 10, spanning the Political Office, Communications Department and Policy Unit, remains largely unchanged, but the people within it have not.
This directory profiles some of the key advisers helping to deliver the Prime Minister’s 10 Year Plan, which Burnham has described as a “circuit breaker for Britain”.

Special Advisers.
Special Advisers (SpAds) are the political eyes and ears of Ministers. They play a crucial role in supporting Government Ministers by providing politically informed advice and assistance.
Distinct from the permanent Civil Service, they ensure the political impartiality of civil servants is maintained by clearly distinguishing the source of political guidance.
There is currently a review of No. 10’s policy, strategy and delivery functions, with conclusions expected in October. As a result, a number of policy roles are being covered on an interim basis by civil servants and direct ministerial appointments.
The review coincides with the expiry of many temporary contract extensions put in place as the Starmer administration drew to a close, so further personnel changes and a significant reshaping of No. 10’s operation are expected this autumn.
