Full Name of Applicant Liam Wilkinson
Title of Former Civil Service Role Head of AI Incubation
Date Left/Retired from the Civil Service 31 March 2026
New Employer Tony Blair Institute
New Appointment/Employment (including when taken up) Principal Applied AI Engineer – 13 April 2026
Department’s Decision on Application (including details of any waiting period or other conditions or restrictions applied) For the remainder of your time in Crown Service, you should not be involved in commercial discussions that could, in future, involve your prospective employer (including parent companies, subsidiaries, partners and clients).

 You do not draw on (disclose or use for the benefit of themself or the persons or organisations to which this advice refers) any privileged information available to you from your time in Crown service.

You continue to review the Business Appointment Rules guidance before accepting any new appointment or employment for two years after leaving the Civil Service to ensure that there is no cause for justified public concern, criticism or misinterpretation. For one year from your last day of service, you should not become personally involved in lobbying the UK Government on behalf of your new employer and/or its clients (including parent companies, subsidiaries, partners and clients); nor should you make use directly or indirectly, of contacts in the government and/or Crown service to influence policy, secure business/funding or otherwise unfairly advantage the Tony Blair institute (including parent companies, subsidiaries, partners and clients). However, this does not preclude you from interacting with the UK Government, provided that it is related to the work of the Tony Blair Institute on matters aligned with government policy. In addition, this does not prohibit you from contacting the Department as part of building and maintaining any day-to-day relationships with government.

Lobbying in this context means that “the former civil servant should not engage in communication with Government - including Minsters, special advisers and officials - with a view to influencing a Government decision or policy in relation to their own interests, or the interests of the organisation by which they are employed, or to whom they are contracted”.
