As speculation abounds that the Government may be considering a delay to Article 50, we took the opportunity of our latest monthly survey of Conservative Party members to ask their view on the idea.

The result was pretty much overwhelming: 82.7 per cent of the 1,257 respondents oppose the idea, while 14 per cent support it.

Notably, this is a higher level of opposition than we found in our snap survey a couple of weeks ago, when 78.7 per cent answered No.

At minimum, grassroots opinion is not softening, and it might even be hardening as impatience sets in. If the Government does intend to try to delay proceedings, then it has a major explaining job ahead of it.
