Leonard, 66, best known for his 15 years as WIN News anchorman, lost a long battle with mesothelioma.

Leonard, originally of Yass, lived in Canberra for more than 50 years. A fixture in the homes of many Canberrans on weeknights, he ended his career with WIN on July 20 last year.

Before his retirement, he told The Canberra Times, ''It's a privilege to do this job. You get a view of the community like no other job lets you, and it really is a privilege.''

Leonard boarded at Canberra Grammar School. He did five years of work experience at Radio 2CA before accepting a position as presenter with the station, where he stayed another 10 years. For the next 20 years, he presented news and current affairs for radio and television at the ABC in Canberra, before joining WIN.

His family led by Leonard's wife, Gwen said in a statement, ''Peter was a wonderful, loving and caring family man.

''While best known as one of Canberra's most recognisable media personalities, his family will remember him as a man who always put the needs of others first, for his wicked sense of humour and his total loyalty and commitment to those closest to him, be they family, friends or work colleagues.''

The family thanked all those who supported him both during his Canberra media career and while he fought his illness.

Funeral arrangements will be announced in the next two days.

Chairman of WIN Corporation Andrew Gordon said, ''The management and staff of the WIN network are deeply saddened. He was a much valued member of the team for 15 years as the face and voice of local news in the ACT.

''He was a mentor to many, a true professional and a charismatic man. Above all, he was our friend and we will miss him.

''Our heartfelt sympathies are with Gwen and his family at this time.''

Friend and former colleague Jeremy Lasek said, ''He was like a father, brother and a good friend all rolled into one.

''I think much of the success of not only WIN News but WIN Television can be attributed to Peter,'' he said.

''He made an enormous contribution, he was passionate about his work, he was totally dedicated and committed.

''He showed great attention to detail and I think he was a remarkable face for the news.

''He was a great supporter of young people starting their careers in the media and generous when sharing his knowledge and expertise.

''I just know everyone who came into contact with Peter had the highest regard for him. He will be very greatly missed.''

Leonard is survived by his wife Gwen, his children Matthew, Nathan and Natasha, and his grandchildren.
