I do not deny for one second that with this county's present hostile immigration policies, it is getting ever harder to find good BIR chefs and standards are falling nationwide.
It's a tricky one Phil.
When you're a member of the EU, the immigration policy pushes you towards recruiting from within the EU (and is supported as that with free movement of labour, no need for work permits, etc.).
If you're not in the EU, it means you (Britain) can decide it's own immigration policy, and take whoever you want, EU or non-EU.
But....if you're not in the EU, you (Britain) don't get such easy access to the large pool of cheap labour, on which many UK businesses have built themselves.
There are no easy answers.
