YouGov - CON 42, LAB 25, LDEM 11, UKIP 12

YouGov's latest voting intention figures are CON 42%, LAB 25%, LDEM 11%, UKIP 12%, GRN 4%. It was conducted over last weekend, so shortly after the Liberal Democrats' success in Richmond Park. The 11% for the Lib Dems equals their highest from YouGov since the election, but it's not a huge bounce and not a record breaker. More notable is the Labour score - 25% is the lowest that Labour have recorded since back in 2009 (as others have commented, it appears to be the lowest they have had in opposition since all the way back in 1983, though that should be seen in the context that there were fewer small parties in the 1980s and the big parties normally had higher scores than are typical these days)
