Re: @AC:This goes to show one thing
"[...] how have you come to the conclusion that there won't be any seasonable labour available for crop picking?"
The BBC "Farming Today programme at 06:45 has often considered the impact. Two factors have been suggested.
One is that EU labour will not have free movement access.
The other is that the drop in the value of Sterling has made the already low rates of pay less attractive to the usual foreign workers.
The need for foreign workers is because people in England generally won't do that type of work. The tourist catering/hotel industry is also fearing the same problems.
Tory minister Priti Patel campaigned for "Leave" on the stated intention of replacing EU immigrant workers with freer access for those from the Indian subcontinent. India/Philippines are also wanting freer access to the UK labour market as a part of any future trade deal. That is unlikely to be fruit/vegetable pickers though.
