YouGov/Sun - CON 36%, LAB 43%, LDEM 9%

Tonight's YouGov poll for the Sun has topline figures of CON 36%, LAB 43%, LDEM 9%. The seven point Labour lead in this poll is the largest YouGov have shown since before Cameron's veto in December. Normal caveats apply of course - true, it could be a sign that Labour's lead is still growing, but if Labour's underlying lead is around about five points as last week's polls were suggesting then a seven point lead would be very much within the normal margin of error. Right now this poll is entirely consistent with last week's.

Tonight's poll also has the fortnightly question on what issues people think are important - note how high the NHS is still scoring. 33% of people picked health as one of the most important issues facing the country, 38% of people picked it as one of the most important issues facing them and their family (second only to the economy). The second of these is at its highest level since last June.

As I've said before, the coverage of the NHS isn't making that much difference to the proportion of people who back the Conservatives on the NHS, because not many people trusted them on the NHS to begin with. On that front it is more likely to entrench existing views of the Conservatives on the NHS than change any minds. What it has done is drive the NHS up the political agenda and make more people consider it a pressing issue (I suspect Ed Miliband's focus on the issue of the NHS is also one of the things that has driven his leadership approval ratings up since January).
