I don't see why either Leave or Remain voters should be blamed for the way that the Tories have handled this. Not only should they have set up a cross party committee with experienced negotiators, they should also have made preparation by, eg, increasing the training of health workers, rather than reducing it, investing in industry, particularly small parties etc., having discussions with smaller countries, many of whom have been very frustrated as they see this as an opportunity for them.
There is nothing about the process that the Tories have got right and yet the people that get blamed are:-
1. Corbyn
2. the EU
3. Leave voters
4. Remain voters.
The Tories don't even seem to be on the list of much of the media and many individuals.
It was always going to be difficult but the public should be able to expect a minimum level of competence from their government.
