Blair Peach, a New Zealand teacher, was fatally injured while taking part in an Anti-Nazi League demonstration against a National Front election meeting in Southall, London.

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.

The Anti-Nazi League (ANL) was an organisation set up in 1977 on the initiative of the Socialist Workers Party (SWP) with sponsorship from some trade unions and the endorsement of a list of prominent people to oppose the rise of far-right groups in the United Kingdom. It was wound down in 1981. It was relaunched in 1992, but merged into Unite Against Fascism in 2003.

The National Front (NF) is a far-right, fascist political party in the United Kingdom. It is currently led by Tony Martin. A minor party, it has never had its representatives elected to the British or European Parliaments, although it gained a small number of local councillors through defections and it has had a few of its representatives elected to community councils. Founded in 1967, it reached the height of its electoral support during the mid-1970s, when it was briefly England's fourth-largest party in terms of vote share.

Southall is a large suburban town in West London, England, part of the London Borough of Ealing and is one of its seven major towns.
