It's expected the president of Italy will ask Matteo Renzi, the mayor of Florence, to take over as Prime Minister. Mr Renzi's engineered the toppling of Mr Letta in an undignified party coup. We'll ask if he's the man to drag Italy out of its economic doldrums.

We'll also head to France to find out why the economy is still stalling.

One of the biggest trends in the US right now on Twitter is #wearethepeople. It's had more than four million tweets since it took off three weeks ago. We'll find out what it is - and what it has to do with the Iraqi dinar.

Also on the programme we'll chat with our special guest Sean Turnell, an economist at Macquarie University in Sydney about the anniversary of GPS and the spectre of recession in Brazil.
