OTTAWA - Stephane Dion has given his stamp of approval for Justin Trudeau to run for the Liberals in the next election, says a senior Liberal insider.

The source said Trudeau, the oldest son of Margaret Trudeau and the late former prime minister, will run in his home province of Quebec, most likely in Montreal.

"He is going to run," said the insider.

The insider said a riding has not been selected but Dion does not want him to run in a safe Liberal riding such as the Outremont riding recent vacated by Jean Lapierre.

The insider said the party wants Trudeau to run in a Montreal-area riding now held by the Bloc Quebecois.

Discussions are underway to find an appropriate riding for Trudeau.
