One of the important wins will be to resume our full voting membership of the World Trade Organisation. (Sat 27-Jul-19 11:24:03)
What is the advantage of this? I am sure Yorath0 that you understand as well as I do that John Redwood is extremely biased when it comes to leaving the EU or remaining in it. So I looked for a more impartial report. "The costs and benefits of leaving the EU: trade effects"[1] is a long and interesting report and worth reading. It will certainly take you away from the "we are right, they are wrong" view although I appreciate you may not be open to such an argument.
What it does tell us is that the general welfare of us all will be affected negatively by twice as much if we have a hard Brexit and move to WTO rules as we would if we had a soft Brexit although, of course, that would also affect us when compared to staying in.
Obviously, there are perceived benefits to leaving outside the downside of these economic losses. But I do not see any argument for this which would not equally support a reform of the EU.
