immigration, identifies the reasons as being "in part because of perceptions about their level of competence and stereotypes about their ability to speak English". Indian workers also faced discrimination from the white-dominated trade unions, and so formed their own organisation, the Indian Workers' Association (IWA). During local elections of the 1960s anti-immigration rhetoric was used by some candidates, successfully in many cases. Smaller right-wing parties used immigration as a platform on which to stand, including in Southall. In the local elections of May 1964, the anti-immigration British National Party (BNP) polled 15 per cent of the vote in Southall; in the general election that October the BNP leader, John Bean, received 9.1 per cent in the Southall constituency. Bean won 7.4 per cent of the vote at the 1966 general election. The BNP's successor, the National Front, recorded 4.4 per cent of the vote at the 1970 general election. In June 1976 the racist murder of Gurdip Singh Chaggar in Southall—outside the offices of the IWA—led to the former chairman of the National Front, John Kingsley Read, stating "one down, a million to go". Chaggar's murder led to the formation of the Southall Youth Movement (SYM) to challenge the rise in racism and attacks from the National Front. Rioting in the area took place between police and Asian youths and members of Peoples Unite, a similar group to the SYM, but consisting of young Afro-Caribbeans. Special Patrol Group The Special Patrol Group (SPG) was formed in 1961 as a specialist squad within the Metropolitan Police. It provided a mobile, centrally controlled reserve of uniformed officers which supported local areas, particularly when policing serious crime and civil disturbances. The SPG comprised police officers capable of working as disciplined teams preventing public disorder, targeting areas of serious crime, carrying out stop and searches, or providing a response to terrorist threats. In 1978 there were 1,347 SPG members in forces across the UK, 204 of them in the Metropolitan Police Service. They were divided into six units, each of which contained three sergeants and 30 constables. Each unit was commanded by an inspector. The use of the SPG proved controversial to some. It was involved in the Red Lion Square disorders, when Kevin Gately, a student demonstrating against a National Front march, was killed from a blow to the head from a blunt instrument; the perpetrator was never identified. Accusations were made that
