Ed Broadbent was, for a brief while in the 1980s, the most popular politician in Canada, scoring higher in public opinion polls than then prime minister Pierre Trudeau.
He stepped down as leader of the federal New Democratic Party in 1989 after what he called a disappointing election result. The party had just won the most seats in its history, but Broadbent wanted more.
Broadbent was coaxed back into politics by then NDP leader Jack Layton. Broadbent ran for, and won, a seat in Ottawa Centre in 2004.
He quit politics in 2005 because of his wife Lucille's illness.
