The Volcanic ash influenced the London Economy because all airports were stopped to work and flights cancelled. Some people were waitting for a long time to take a other flights. I think this natural disaster cost around 1 billion EUROS.
In my opinion about economy of France was in difficulty to grow up, the number of unemployee increase everyday, so why some people would like more decision to help us for them problem of housing, health, education, money. Some people would to abroad in the better country.
