DMcG I do not know why you linked to a yougov survey. According to Jim Carroll (Date: 10 Sep 18 - 08:27 PM )
"- it's a 'survey' from a multi-million stock-exchange marketed company named You-gov with Conservative Party connections whose surveys are all carried out on the internet"
or at least that is the response I received when quoting it one time. My feeling is that like many surveys, it may attempt accuracy,but does not always achieve it.


I suspect labour takes a heartland hammering next time around if they betray brexit. After all brexit support is an integral part of their manifesto, unless they are deceiving their electorate.
What happens after the vote will probably be a sea change of British politics, and Corbyn will be between a rock and a hard place.(as will May)
