Former Edmonton MP and senator Doug Roche has been nominated for the Nobel Peace Prize.

Roche was nominated for the 2011 award by the International Peace Bureau.

"Aside from existing Nobel laureates, it is hard to think of a single individual who has worked as hard for disarmament as he, and with such persistence and determination, at the top levels of world politics," the bureau wrote in its nomination letter.

Roche served as the Progressive Conservative MP for Edmonton-Strathcona and Edmonton South from 1972 to 1984. He was appointed to the Senate in 1998 and retired in 2004.

Roche focused on peace and security issues throughout his career. He served as Canada's UN Ambassador for Disarmament from 1984-89.

Roche's latest book, How We Stopped Loving the Bomb: An insider's account of the world on the brink of nuclear disarmament, will be published in March.

Last year, the city of Hiroshima named Roche an honorary citizen for his work in nuclear disarmament.

The Nobel Peace Prize is awarded annually by a committee of five people chosen by the Norwegian parliament.
