Robin Sears, Brian Mulroney's spokesperson, says at least six MPs and cabinet ministers called the former prime minister to express their sympathy and indignation regarding the kerfuffle over his Conservative party membership.

It seems these calls are in direct defiance of Prime Minister Stephen Harper's order. He told his caucus to have no contact with Mulroney.

Back in November 2007, Harper said: "I think it will be incumbent upon myself and also members of my government not to have dealings with Mr. Mulroney until this issue is resolved."

At issue is the business relationship between Mulroney and businessman Karlheinz Schreiber. The Oliphant Inquiry is delving into their dealings and last week, as the inquiry got underway, word came from Harper's office that Mulroney is no longer a member of the Conservative Party.

Mulroney was dumbfounded.

Through Sears, Mulroney said the allegation was completely untrue. " I will be a conservative until I die," Mulroney insisted.

Sears says not only have many Tories called to express their dismay, but Liberals Michael Ignatieff and Bob Rae also called Mulroney.

Sears says it's not wise to push Mulroney's patience.

"At some point, he may feel he has to say something publicly. That's something I hope that those who are thinking about launching another attack think carefully about before they do."
