The poll, conducted by think tank More in Common, suggests that 49 per cent of respondents want the UK to continue its membership in the ECHR.

Forty-one per cent of respondents said that a Conservative pledge to leave the ECHR would make them less likely to vote for the party. A mere quarter, 26 per cent, said it would make them more likely to do so.

This data emerges amidst discussions within senior Conservative ranks, suggesting prime minister Rishi Sunak should commit to an ECHR exit in the forthcoming general election. Support for the move comes from a belief that it would simplify the deportation of illegal migrants and foreign criminals.

Suella Braverman, the home secretary, supports the UK’s withdrawal from the ECHR.

Immigration minister Robert Jenrick said that the UK might consider parting ways with the ECHR if the Supreme Court finds the Rwanda policy illegal.

The current government is striving to reverse the Court of Appeal’s verdict, which declared the Rwanda policy unlawful. The court’s judgment stemmed from concerns that deporting migrants to Rwanda might result in their further deportation to their home nations, where they could face persecution, violating the ECHR’s standards.
