I'm not being horrible mate, but numerous polls this week have put Labour 10+ points ahead. The Survation one will further validate this (and is the most reliable polling company).
This will also not be a "short term hit" for the Conservatives. I have spoken at great length, on numerous occasions, often to quite derisory people who crowed about polls before Brexit that we needed to wait until the end of March and you would see movement. This has been proven completely correct, polls remained stable, both sides essentially trading leads, and subsequently the Conservatives have collapsed.
I will make another prediction (which is more a reiteration of what I said previously) and it is that this will not be a short term collapse for the Tories. The Parties ratings are worse than May's. The major opponents ratings are worse than May's. The governments ratings are worse yet. This will not be turned around quickly. They will be obliterated in the next (May) elections. There are a host of other issues to add in, but they are not turning this around, this is the start of a process for them, and the question is really about how to best limit damage, as opposed to how to turn it around.
In the last 100 years, Labour have won 1 election where they have enjoyed a 10+ lead. This is not a realistic standard for not being embarrassing. A 10+ lead (which Labour is now regularly showing) is a remarkable achievement and not one to be scoffed at. The one occasions they did it, they would also have not done so, with the current lie of the land in Scotland.
