Canadian news viewers found out yesterday that after almost 30 years as anchor of CBC's flagship news program, Anchor Peter Mansbridge will leave the The National next summer.

Mansbridge told viewers during Monday night's broadcast that he will step down after anchoring the network's Canada Day coverage next July 1, when the country will mark its 150th birthday.

"This next year will mark 30 years since I was named chief correspondent and anchor of the National ... a position that's an honour and a privilege to occupy," Mansbridge said.

"It's been an amazing time to help chronicle our history, but I've decided that this year will be my last one."

Mansbridge's career has spanned nearly five decades, including 28 years at the helm of The National as anchor and chief correspondent.
