The Cabinet Confidential series
As the Prime Minister’s senior civil servant in the country, a Cabinet Secretary usually operates behind the scenes rather than in the spotlight and has a relatively low media profile. Now for the very first time five former cabinet secretaries – Robert Armstrong, Robin Butler, Richard Wilson, Andrew Turnbull and Gus O’Donnell will be providing new and compelling material about their role.
The Cabinet Confidential series was funded by Queen Mary, University of London’s Centre for Public Engagement It was produced by academics and students from the Mile End Group, Queen Mary’s forum for government and politics, in partnership with Mile End Films the University’s in-house production unit.
