A new poll finding shows that the proportion of British voters who believe migration has been "mostly bad" for the UK has risen by almost a third over the past decade, according to the Daily Mail. The shift is attributed largely to the continued failure of successive governments to curb Channel crossings by small boats, with the issue remaining one of the most politically charged in Britain.

Notably, the survey suggests the hardening of attitudes is not confined to traditionally Eurosceptic or Leave-voting groups, with a growing number of people who backed Remain in the 2016 EU referendum now also expressing negative views on migration's impact. The trend comes against a backdrop of record numbers of small boat crossings and repeated ministerial pledges to "stop the boats" that have yet to materially reduce arrivals.
