Background

Before the Act was passed, citizens of Commonwealth countries had extensive rights to migrate to the UK. For instance, in the sparsely populated frontier area of San Tin in Hong Kong, 85–90 percent of the able-bodied males left for the United Kingdom between 1955 and 1962 to work in British factories, foundries, railways, buses, hotels, and restaurants.[5]

There was widespread opposition to mass migration in Britain from a variety of political groups, including the Conservative Monday Club, whose Members of Parliament were very active and vocal in their opposition thereto. In response to a perceived heavy influx of immigrants, the Conservative Party government tightened the regulations, permitting only those with government-issued employment vouchers, limited in number, to settle. The leader of the opposition in Parliament at the time, Hugh Gaitskell of the Labour Party, called the act "cruel and brutal anti-colour legislation".[6]
