A state funeral is being held Sunday in Ottawa for former NDP leader Ed Broadbent.

Broadbent, who died on January 11 at the age of 87, served as a member of Parliament for over twenty years and led the NDP for 14 years in the 1970s and 1980s.

Prime Minister Justin Trudeau will be attending the funeral.

Trudeau said a state funeral for Broadbent will provide an opportunity for Canadians to pay tribute to his legacy, which includes leading the NDP to its best electoral results until Jack Layton broke that record in 2011.

While state funerals are typically held for current and former governors general and prime ministers and sitting cabinet ministers, the prime minister is able to offer one for any eminent Canadian.

Flags on all Government of Canada buildings across the country, including the Peace Tower, will fly at half-mast from sunrise to sunset on Sunday.
