The DUP's Peter Robinson has used parliamentary privilege to claim that a leading Belfast businessman is linked to what he termed "IRA dirty money".
Peter Robinson used parliamentary privilege to make claims
Mr Robinson said Peter Curistan was a key investor in the Odyssey Centre in his East Belfast constituency.

He challenged Mr Robinson to repeat his claims outside of parliament.
