Who was the last most famous and popular leader of the UK legal and registered Communist party?
How did his leadership compare to that of previous leaders of the party?
Robert Griffiths was known for his emphasis on grassroots organizing and promoting socialist policies that were relevant to ordinary people. Some have compared his leadership to that of Harry Pollitt, who was one of the most influential Communist leaders in Britain during the mid-20th century.
