The Advisory Committee on Business Appointments is an non-departmental public body in the UK, which was set up in 1975 to provide advice on applications from the most senior Crown servants who wish to take up outside appointments after they leave Crown service. Since 1995 it has also provided advice to former Ministers on their employment in the two years after leaving office. The committee is chaired by Lord Lang.
In March 2010, the Advisory Committee on Business Appointments revealed that Tony Blair was involved in business consulting to an oil firm with interests in Iraq. Blair had managed to prevent the committee from publicizing the news for almost two years until it finally decided to release the information to the public.
