Cabinet rift? MacKay defies Harper:
CTV News has learned a weekend letter on the Atlantic Accord dispute has left Prime Minister Stephen Harper facing a major cabinet split.
Sources say that Foreign Affairs Minister Peter MacKay feels blindsided by the letter to the editor published Saturday that inflamed matters.
Insiders say that Sandra Buckler, the prime minister's communications director, instructed MacKay to sign the letter, which rejected any side deals with Nova Scotia.
MacKay, a Nova Scotia MP and the senior minister for Atlantic Canada, refused, say sources. Finance Minister Jim Flaherty signed the letter.
Robert Fife, CTV's Ottawa bureau chief, reports that MacKay is trying to broker a deal with MacDonald and convince Harper that if he doesn't compromise, he could pay a high political price.
