Deborah Cleland Grey (born July 1, 1952) is a retired Canadian politician who served as the leader of the Official Opposition in 2000, from March to September.

[2][3] Born in Vancouver, British Columbia, Grey pursued studies in sociology, English and education at Burrard Inlet Bible Institute, Trinity Western College and the University of Alberta.

Grey's first run for office was in the 1988 election, when she ran as the Reform candidate in Beaver River, a mostly rural riding in northeastern Alberta.

Grey moved to Edmonton North at the request of several local conservatives dissatisfied with being represented by a Liberal, John Loney (elected in the 1993 landslide).

She held the post until new Alliance leader Stockwell Day was elected to the House of Commons in September 2000.

Grey was co-chair, with former PC leader Peter MacKay, of the new party's first leadership convention in March 2004.

She called Jean Chrétien "the Shawinigan Strangler", Don Boudria "Binder Boy", Jane Stewart "Miss Management" and Paul Martin "Captain Whirlybird".

Later she bought her way back into the pension plan resulting in former Prime Minister Joe Clark labelling her the "high priestess of hypocrisy".

It was announced that Grey was stepping down from the Security Intelligence Review Committee on May 1, 2015, in a press release from the Prime Minister's Office.
