OTTAWA -- Former Quebec bar president J. Michel Doyon has been named the province's new lieutenant-governor.

The historian and former university lecturer will replace Pierre Duchesne, who has held the post since 2007.

Prime Minister Stephen Harper made the announcement in a statement this afternoon.

Doyon is also an ex-member of the board of directors of Radio-Canada, the CBC's French-language service.

Lieutenant-governors are appointed by the Governor General on the recommendation of the prime minister.

They serve as the official representatives of the Queen in their respective jurisdictions. The job is largely ceremonial, but bills cannot officially become law until signed by the lieutenant governor.
