My main concern is probably medication supply - one in particular can be hard to get at the best of times.
Possibly rising prices on everyday goods - nothing too catastrophic probably.
Nothing else should affect me too drastically I don't think.
I'm in a pretty quiet residential area, so if there are riots, I can avoid the town near me in London most likely to see them and go to another town/shopping area.
My other concern would be welfare cuts in a next budget - not sure when the next budget is?
