Cope took on the role of secretary of state in charge of relations with Parliament last week, following President Jacques Chirac's 5 May re-election to a five-year term as French head of state.
The government spokesman also holds the title of Mayor of Meaux in France and is considered a close Gaullist aide of Chirac.
Copé is a graduate of Ecole Nationale de l'Administration (ENA) and is a specialist in finance.
Speculation suggests Copé was also hoping for the role of Minister of the Budget in the new government.
In his communications role, he will hold responsibility for all official statements to be made by the Government and Raffarin.
He is also understood to be providing ad hoc communications advice to President Chirac.
Prime Minister Raffarin is expected to place added emphasis on communications within the Government due to his background in marcoms and PR.
Prior to his career in politics, Raffarin worked as director of marketing for French coffee brand Cafés Jacques Vabre.
He also worked for a number of years at French PR agency Bernard Krief Consulting, headed by president Louis Petiet.
The agency is known for its political lobbying work and communications strategies among a range of PR offerings.
Raffarin is widely speculated to have become an unofficial image counsellor to Chirac in recent years and is believed to have helped provide behind-the-scenes advice for the President's recent winning campaign.
