Former trade union leader Jack Jones has died aged 96, his son said.
Mick Jones said his father, who led the Transport and General Workers' Union, died in London shortly after 9.30pm on Tuesday.
He said: "He passed away very peacefully in a very nice care home in Peckham."
He continued: "He had all the care he could possibly want. He was active until the very end and had a good innings."
Mr Jones was born in Liverpool and served as general secretary of the TGWU from 1969 to 1978 when it was one of the most powerful unions in the country.
Former TUC General Secretary Norman Willis said Mr Jones would be remembered as a "fighter" for ordinary people.
He said: "I worked with Jack in the TandG and through the TUC for many years.
"Jack Jones was a great fighter for ordinary people whether they were at work or unemployed or later as pensioners.
"He never forgot the underdog and will be remembered with affection."
