This follows proposals announced last year to increase democratic scrutiny of important public appointments.
Richard Thomas, the current information commissioner, retires on 30 June. Thomas has taken a firm line against government departments that have breached the terms of the Freedom of Information Act. He has fought for Gateway reviews to be published. He has issued warnings about the database state and data losses.
