The point I was making, which is a follow up to what I have stated before, is that the European Central Bank cannot call on us to bail out banks in Spain, France, Germany etc. because we are NOT in the Euro and the ECB does not control us. It does control all of the countries in the Euro.
However, there is a downside in that our BofE and HMG managed to cause a bank run due to their incompetence whereas the ECB has managed to provide liquidity and support without causing a run. Northern Rock would not have been nationalised under the ECB, that's for sure, as liquidity would have been provided quietly and anonnymously.
