Leighton Rhett Radford "Darcus" Howe (26 February 1943 – 1 April 2017) was a British broadcaster, writer and racial justice campaigner. Originally from Trinidad, Howe arrived in England as a teenager in 1961, intending to study law and settling in London. There he joined the British Black Panthers, a group named in sympathy with the US Black Panther Party. He came to public attention in 1970 as one of the nine protestors, known as the Mangrove Nine, arrested and tried on charges that included conspiracy to incite a riot, following a protest against repeated police raids of The Mangrove restaurant in Notting Hill, London. They were all acquitted of the most serious charges and the trial became the first judicial acknowledgement of behaviour (the repeated raids) motivated by racial hatred, rather than legitimate crime control, within the Metropolitan Police. In 1981, he organised a 20,000-strong "Black People's Day of Action" in protest at the handling of the investigation into the New Cross house fire, in which 13 black teenagers died.
