On June 23 Britons go to the polls to decide if their country should leave or stay in the European Union. The campaign issues on Brexit or Bremain - whether Britain exits or remains - include immigration, welfare payments to migrants, security and keeping the pound. Tim Bale is professor of politics at Queen Mary University in London and a former lecturer at Victoria University in Wellington. He talks about the debate which, according to one newspaper, has been "characterised by bias, distortion and exaggeration" - and that, says Tim Bale, is putting it mildly.
