Labour peer Andrew McIntosh has died after a battle with cancer, relatives have said.
The 77-year-old politician, who served as a whip and a culture spokesman in the Lords, was given a life peerage in 1983 as Baron McIntosh of Haringey.
His son Philip said: "He was the most honest and considerate socialist politician of his generation and will be greatly missed."
Lord McIntosh, who lived in Highgate, north London, was leader of the Labour group which won control of the Greater London Council in 1981.
But the day after victory he was ousted, with Ken Livingstone voted leader in his place.
His son said funeral arrangements were being made for a humanist ceremony on September 8.
Lord McIntosh, who was married to social researcher Naomi Sargant, had two sons and a stepson.
