Freedom of Travel & John McDonnell

McDonnell was stated to have said that Labour no longer needs to defend free movement of labour because that has now gone, following the decision of the public to vote to leave the EU.
It is only a matter of time before the electorate realise that BREXIT will have no impact on immigration. Migration is a 2-way process and there are as many ex-pat BRITS in the EU as there are EU citizens in the UK, about 2.8 Million. The published disparity arises because the figures oft quoted are for people who have an NI number or similar for the EU. It ignores the huge number of Brits who simply live in Europe.

So whereas we are now all free to go and live, work or retire anywhere in the EU (subject to the condition that you can support yourself, else you have to go home after 3 months). In future we will have to ask permission from the receiving State. Similarly EU citizens are currently allowed to come here again on condition that they 'are not a burden on the state' or they get kicked out after 3 months. Employers can select from a huge pool of talent from the whole EU, I know 'cos I regularly run interview panels - but in future the State will decide who can come and work here not employers.
BREXIT has taken away our freedom to travel, and our freedom to recruit the best person for the job. Isn't that the sort of thing that Jo Stalin did? I know that is as extreme analogy - but it is time that BREXIT accepted that our personal freedom has been undermined.
My other moan is that BoJo keeps talking about building trading links outside of the EU. But I can do that now - our company already exports to the Far East, Australia, Japan, the US, Canada and even on occaisions to Russia and South America. We have been given nothing. Yet in return for nothing we are now going to be locked out of the biggest free trade area in the world.
Returning to McDonnell, if he cannot articulate support to retain our freedom of travel then IMO he too should stand down with Corbyn.
