Dickie joins on 10 February after spending two years as regulatory affairs director at the European Competitive Telecoms Association.
BBC director of public policy Caroline Thomson said a key area for Dickie would be the progress of the Communications Bill through Parliament.
Dickie added that the Government's review of the BBC, which was announced earlier this month by culture secretary Tessa Jowell, was also a key policy issue.
The review comes ahead of the renewal of the BBC's charter in 2006. Earlier this week Barry Cox, a media adviser to Government, called for the abolition of the licence fee and the setting up of a public service broadcasting fund available for all broadcasters.
Dickie, who is a former GPC consultant, will work closely with BBC public policy controller David Levy.
The political and parliamentary role was previously handled by Michael Hastings, who now heads the BBC's CSR unit (PRWeek, 18 October 2002).
