A 1966 photograph, taken probably in northern England, of a bus conductor wearing his uniform together with the turban, the distinctive mark of his Sikh identity. According to Sikh law, the turban must not be covered or replaced by any other cap or hat. In the 1960s several campaigns were mounted to permit Sikh employees of bus companies in England to wear the turban and not the uniform cap. In 1982 the House of Lords ruled that Sikhs were a separate ethnic group effectively entitling them to wear turbans in all walks of life.
