Do we really care whose warped view fails to value sovereignty ? Remoaners seem to get everywhere.
Let's be quite clear here, Brexit is not responsible for reduced exports no matter whose fantasy that is. All it took was a little decency from the EU, in place of their deliberate obstruction, and trade between us need not have changed. And as any nation outside the EU is perfectly capable of not letting our EU exit affect trade either, Brexit can not be the cause of any issues there. In fact new trade agreements are being added as we go.
The real issue is, and clearly remains so from the continuous stream of critical threads, the power plays from various groups and their supporters who have nothing better to do than push propaganda against even their own nation. They should be ashamed not to support the UK in the face of external political shenanigans trying to take advantage of the UK, but they'd rather denigrate their nation instead. A peacetime version of fifth columnists.
