There is nothing to prevent Greece once again being a successful country "except sometimes bad politics," says Jose Manuel Barroso, the former president of the European Commission.

Talking to Ben Thompson for Business Live on BBC World News, Jose Manuel Barroso said the new Greek government "lacks experience" and came to power with "completely unrealistic promises" to the Greek people.

On the topic of a UK referendum on continued membership of the EU, Mr Barroso said it would be a defeat for all those in Europe if the UK left.

He went on to say that individual countries do not have the same leverage in the world as they would if they were part of the EU.
