Brownlee says threats against MPs have worsened significantly

New Zealand MPs are facing growing threats and abuse, prompting Parliament to ramp up security. Speaker Gerry Brownlee says the situation has worsened significantly, with a specialist parliamentary security team handling more than 200 requests for help in just three weeks. It comes as Australian MP Helen Haines remains in a critical condition following a serious attack in her constituency. Gerry Brownlee spoke to John Campbell.
