YouGov - Tories take 18 point lead

YouGov's monthly poll for the Telegraph shows a massive 18 point lead over Labour. The full topline figures are CON 44%(nc), LAB 26%(-2), LDEM 17%(nc).

The poll was conducted between the 21st and 23rd of April, so while the 10p row was at its height, but almost entirely before the government announced their change of policy Wednesday lunchtime. It goes without saying that the poll shows the exactly opposite trend to ICM's earlier this week, which suggests one (or both) of the polls are outliers. Certainly given the mess the government was in when this poll was being taken, a fall in Labour support seems prima facie more likely, but we'll see.

This is the largest poll lead the Conservatives have achieved since 1987, and the lowest Labour share of support I can find since the aftermath of their 1983 rout, though I don't have very complete records of opinion polls prior to 1987. If repeated at a general election it would produce a Conservative landslide majority of 154, with Labour down to 190 seats.
