Immigration in British society became a more politically prominent and divisive issue in the 1960s. The decade saw legislation introduced – in 1962 under the Conservatives; in 1965 and 1968 under Labour governments – which imposed controls on Commonwealth immigration, as well new laws on race relations in 1965 and 1968. Prominent Conservative politician Enoch Powell made his highly-controversial ‘rivers-of-blood’ speech in April 1968, which led to widespread condemnation across the mainstream parties but also elicited significant public support for Powell’s comments. Polling was carried by NOP to gauge the public’s reaction to this legislation, to Powell’s intervention and to other aspects of the issue. The polling sheds light on the overall nature of public attitudes and of areas of consensus and disagreement across different groups in society.
The legislation on Commonwealth immigration obtained widespread public support. In August 1965, 88% backed the Labour government’s legislation, with 5% saying it was wrong, with large majorities in favour among supporters of the main political parties (89% of Conservative voters and 90% of Labour voters).

In March 1968, 79% supported the Labour government’s latest immigration bill, and 15% opposed it. As in 1965, there was similarly widespread backing among supporters of the main parties (78% of Conservative voters and 81% of Labour voters).
Polling asked directly about positions held on immigration. Please note that some language used in the question wordings from the 1960s is not acceptable in contemporary British society (ie in the 2020s). The public was against a complete ban on ‘coloured immigration’ when asked in March (before Powell’s intervention in the debate) and October 1968, with 56% and 54%, respectively, disagreeing with such a policy. In October 1968, support for such a policy was somewhat higher among Conservative (46%) than Labour (37%) supporters.

NOP carried out polling in response to Enoch Powell’s deeply controversial ‘rivers of blood’ speech, delivered in April 1968 to an audience of Conservative Party activists in Birmingham. A range of questions were asked to gauge public opinion, including about Powell’s views and his sacking from the Conservative shadow cabinet, where he was shadow Secretary of State for Defence, shortly after making the speech.
A poll carried out by NOP in April 1968 soon after Powell’s speech showed that key parts of his claims about the deleterious impacts of immigration on British society and the measured needs to address this – which received strong criticism within and beyond parliament – received broad public backing. The polling data shows that:
- 93% agreed with a ‘drastic reduction on further immigration’;
- 78% agreed that ‘that there is a danger of racial violence in Britain unless the inflow of immigrants is cut down by Government action’;
- 64% agreed that ‘immigrants already in Britain should be encouraged by Governments grants to return home’.
On the issue of the Labour government’s Race Relations Bill of 1968 (the first Race Relations Act became law in 1965), attitudes were broadly split over its provisions which made ‘it an offence to discriminate on grounds of colour’, with 45% approving and 46% disapproving.

In May 1968, is clear that support for the views expressed by Powell was broad-based, both in general (67% agreed, 19% disagreed) and across party supporters and socio-economic groups. But Labour and Liberal supporters (both 58%) were somewhat less likely to express agreement than were Conservative supporters (75%). There was also widespread disagreement with Powell’s sacking from the shadow cabinet by Conservative leader Ted Heath (61% wrong, 25% right) and this is again evident across supporters of the major parties and among different socio-economic groups. In this instance, there was little difference in the views of Conservative supporters (25% right, 62% wrong) and Labour supporters (27% right, 60% wrong).
