If you look at things from a purely economic point of view, leaving the EU is not a sensible option without some form of trade agreement in place. One that gives the UK access to the European market without changes in Tariffs. A hard Brexit will serve no-one in the short or long term, because the short term damage will take far too long to recover from.
We are not equipped logistically to overcome all of this, and those that speak about the speed of getting free trade deals with other countries quickly on the leave side have no idea how it works, as has already been evidenced by the fact that Fox and Davis prophesy's on the ease of doing deals with Europe has been shown to completely misunderstand the position. Naddine Dorries has consistency proved she doesn't know what she is talking about on any level and I feel sorry for the constituency that has her as an MP.
I'm going to ignore the fact that the leave campaign has broken the law in getting a leave result, or that no-one can point to a single positive economic factor from Brexit.
I think what is more telling is that the rhetoric has changed from the leave side to pin the blame for the sh*how we are currently in, to being the fault of the people who don't want to leave.
Lets also have a quick look at those who were heading leave from the Government side, David Davis and Boris Johnson have both refused to publish a leave plan (despite promising to do so) as they cant actually put one that works. JRM has moved his hedge fund to Ireland to stay in the EU citing in its documentation because of uncertainty about Brexit. Nigel Lawson has taken French Citizenship, Nigel Farage has a £75K EU pension, and his children have obtained German Citizenship (His ex wife being German). John Redwood has advised companies not to invest in this country because of the decline in markets following Brexit. James Dyson has just signed a deal to manufacture his electric cars in Singapore, as Singapore has just signed a Free trade deal with the EU so he will have no tariffs to pay whereas he will in a post Brexit Britain.
All government statics show we will be worse off as a country, but hey who needs experts.
I would be happy to be wrong, but remain to be convinced that leaving rather than reforming the EU is the way to do it. As for a second referendum, on this I agree with Keir Starmer, there should be a peoples vote on the deal with an option to remain.
