Eurozone break-up: Lord Wolfson and Roland Rudd

Simon Wolfson, who organised a competition to find the best plan for dealing with a eurozone break-up, says that it looks increasingly unlikely the eurozone will "muddle through".
The Conservative peer told the Daily Politics that the issue of employment and growth in the southern European countries was not being addressed.
Businessman Roland Rudd said a eurozone break-up would be "horrific and lead to a far worse situation than we have got now".
