Now this could hurt us.
Stopping our exports of foodstuff will be bad enough. Russia will seek alternatives from world markets meaning that there is less to go round - prices will rise. And if the threat to EU and US flights over Russian airspace comes to pass it will have an added impact - a game changer. A country's airspace reaches to the top of the atmosphere and we do not have planes to fly that high. Let's hope that Vladimir keeps his hands off the gas and oil taps.
It might be time to start thinking of getting in some tins and packets with a long shelf life, just in case.
