The head of the International Monetary Fund is warning of terrible economic consequences, if Britain leaves the European Union.

Christine Lagarde is the latest high profile figure to raise the prospect of severe problems if there is a Brexit.

She said interest rates could rise sharply, and there could be a recession and greater unemployment.

"The forecast, the scenarios that have been done by many - it's all pretty negative."

The referendum on staying in or leaving the EU is now just six weeks away.
