Good thread. I agree, local suppliers need supporting, however, I beleive that the nation needs to look at itself as local as no one area of the UK provides more quality then the nation combined. I always tell chefs to source quality locally first. Then, when quality is exhausted, they can go sa far a field as they need to within the UK.
For this reason you don't see deer trotting down Kensington High Street or find lobster pots in the Thames outside the Houses of Parliament.
