Sarah Montague speaks to EU finance commissioner Pierre Moscovici, who will play a pivotal role in negotiations with Europe under pressure to write off some of Greece's debts, asking whether Europe's taxpayers should spend more to make life easier for the Greeks. If some debt is written off, there is the risk that other countries could ask for the same treatment, but if it is not, then Greece will most likely be forced out of the Euro. In either case there are extremely difficult times ahead for the European Union.
