This week's YouGov / The Sun voting intentions and government approval ratings are the worst for the Conservatives since the election. The net government approval rating is zero - 40% of people approve of the government's performance, but 40% of people disapprove. On voting intention the Conservative lead is down to 2 points, the lowest since the election campaign. Topline figures are CON 41%, LAB 39%, LDEM 12%.

Government approval has been on a slow downwards trajectory since its peak straight after the emergency budget in June. This has been partially down to Labour voters' hardening disapproval of the government, and partially due to falling Liberal Democrat support. The remaining Liberal Democrat voters still say they approve of the government's performance, but there are far fewer of them.

In voting intention, the level of Conservative support actually remains strong. Our daily polling has shown them consistently at or above 40% since the budget, significantly above the 37% support they received at the general election. Their narrowing lead in the polls is actually down to Labour increasing their support off the back of the collapse in Liberal Democrat support. Labour are consistently polling at around 37%, up 7 from their general election score, while Liberal Democrat support stands at just over half their general election vote.
