Gerry Adams in "£5 billion" RHI cost gaffe

We've been hearing for months that the RHI scandal could cost taxpayers up to £490 million. It was cited by Sinn Fein's Martin McGuinness as the main reason for his decision to resign as deputy first minister. So wouldn't you expect their president, Gerry Adams, to be across such an important detail? You'll be able to have a listen to what he said on RTE radio yesterday. Stephen was joined by former Sinn Fein MLA Daithi McKay and commentator Malachi O'Doherty.

Also on the programme, a campaign for all taxis to be allowed in Belfast's bus lanes - does that sound like a good idea?

And, Stephen was talking to broadcasting legend Sir Trevor McDonald about more than 50 years as a hard-hitting journalist.
