Brian Mulroney says European Union 'could collapse' if U.K. leaves

BrianMulroneyis warning thatCanada's proposed free trade deal with the European Union would fail if Britain votes to leave the EU.

"We would have lost our biggest proponent and our strongest advocate" for the Comprehensive Economic and Trade Agreement (CETA), the former prime minister told CBC News. After eight years of negotiations, theCanada-EUdeal has yet to be ratified.

Mulroney spoke at a closed-door meeting of the Canada-U.K. Chamber of Commerce on Friday at the House of Lords in London. In his speech, entitled "A Momentous Decision With Consequences Beyond Britain," he told Britons the EU "could eventually collapse or be significantly weakened by the profound impact of a U.K. departure," according to a copy of his prepared remarks obtained by CBC News.

Canadian model 'not on'for U.K.

The leading campaigner in Britain's "Leave" camp, former London mayor Boris Johnson, has often cited CETA as a model the U.K. could replicate if it leaves the EU.

Not so, says Mulroney, who spearheaded and signed the North American Free Trade Agreement in 1992.

"I think our friend Boris is off on the wrong track," he says. The Leave campaign is "assuming that the United States is going to give them a free trade agreement and that Canada will give them a free trade agreement after they leave Europe, that's not on."

Johnson recently told CBC News that Canada-U.K. relations "would be stronger than ever before" if Britons vote to leave the 28-member bloc.

When asked aboutMulroney's comments on CETA's fate under a Brexit scenario, International Trade Minister Chrystia Freelandspoke about the importance of Britain staying in the EU.
