Clement Blair Peach was a New Zealand teacher who was killed during an anti-racism demonstration in Southall, London, England. A campaigner and activist against the far right, in April 1979 Peach took part in an Anti-Nazi League demonstration in Southall against a National Front election meeting in the town hall and was hit on the head, probably by a member of the Special Patrol Group (SPG), a specialist unit within the Metropolitan Police Service. He died in hospital that night.
