Brian, the Northern Rock affair was entirely different.
In 2008, starting with Northern Rock, a whole series of banks went short of cash, not because they were bankrupt, but because a substantial part of their assets had dropped in value.
Here we have the euro that is about to crash, because State treasuries in Euroland have run out of cash, have no asstes and have only debts. Something entirely different.
If Euroland can hold out till Christmas, we in Britain will have more time to get our act together.
After which it will be a Dunkirk-style evacuation
If the euro collapses after Christmas, it won't matter.
