YouGov/Sunday Times - CON 37, LAB 41, LDEM 10
Tonight's YouGov/Sunday Times poll has voting intentions of CON 37%, LAB 41%, LDEM 10%. A four point lead is the lowest YouGov have shown this month.
Of course it's possible that the government have recovered a bit - Cameron has spoken out against the prisoners voting,
shut down the forestry commission issue and launched their universal benefit reform - but I'll just add my normal caveat about being cautious about any poll showing a shift until it's confirmed by other polls. It may be a sign of the lead narrowing a bit, or it may just be an outlier.
