YouGov/Sun - 37/42/9

Tonight's YouGov/Sun daily poll figures are CON 37%, LAB 42%, LDEM 9%. Leaving aside that single poll showing Labour and the Conservatives equal on 41% - which in hindsight must have been an outlier - there seems to have been a significant shift in YouGov's daily polling over the last week, with the Labour lead widening from around 3 points to 5 points or more, and the Conservatives dropping below 40% to the mid to high thirties.
