Payment protection insurance (PPI) was a con, it was widely mis-sold by people who basically lied about the benefits of these schemes in order to make a lot of money - and eventually, this was recognised and the guilty companies were fined and the victims compensated.
I see a parallel in this referendum. The Leave campaign consistently lied and 'mis-sold' their case for their own ends. They mis-represented the facts to an extent that, if they had been selling a product they would certainly have been prosecuted - yet the consequences of the referendum are far greater.
So isn't there a very good case for challenging the legality of this process?
