I've got quite a bit of fish that I buy fresh, then clean and freeze, but I always keep a good supply of that in the freezer anyway, and most of the other stuff I buy: vegetables and salad stuff appears to be grown here and would anyway be difficult to stockpile. Certain fruits might be an issue but I'm sure I can manage without.
Other things like tinned tomatoes, pulses, nuts, coffee, I usually have a good supply of anyway.
I live on my own but I realise it's going to be a lot more difficult for families if things do get really short.
I think the biggest worry for me, and for a great many people, is going to be the medicines they need, which are not produced here, but as far as I can tell the government are stockpiling certain essential medicines.
I suspect though, that this vote tonight is not going to change a great deal in the short term.
Just wish the whole situation hadn't happened. Bloody David Cameron has got a lot to answer for, but he's sodded off, and unlike the vast majority of people on this benighted island, if everything goes horribly wrong, he's got a nice soft cushion to land on in the form of his wealth, as do most other members of the government who are responsible for the bloody awful mess we're in.
