The study, conducted over the last two years, also reflects widespread frustration at the government’s handling of immigration, with only 15% of respondents feeling ministers have managed it competently and fairly.

On balance, the UK population appears to be slightly more positive than negative about the impact of immigration; however, 40% of respondents agreed that having a wide variety of backgrounds has undermined British culture.

More than a quarter of people believe MPs never tell the truth about immigration and half the population wants to see a reduction in the numbers of low-skilled workers coming into Britain from the EU.
