Rishi Sunak’s approval rating slips as big summer push fails to spark revival

Prime minister drops further in opinion polls after populist policies on migrants backfire

Rishi Sunak's approval ratings have failed to improve over the summer political break - despite several weeks of Tory policy blitzes intended to win back voters.

The latest Opinium survey for the Observer shows the Conservative have failed to shift the dial in Sunak's favour, with the prime minister dropping two points in the past two weeks to a net score of -25% (24% approve, 49% disapprove).
