Green MP Benjamin Doyle speaks on social media posts

The Green MP Benjamin Doyle has dug in - insisting they've done nothing wrong in regards to their social media posts - though admitting they were politically naive. It's the MP's first public comments since the New Zealand First leader Winston Peters launched an attack last week, questioning the appropriateness of language on Benjamin Doyle's private Instagram account - "Bible-belt-bussy." Deputy political editor Craig McCulloch spoke to Lisa Owen.
