Winston Peters has compiled the data on MPs ejected from the House by the Speaker, and found that yes, there's a pattern:
Opposition Members of Parliament are more than twice as likely to be expelled from the House as government MPs since National has become government, says New Zealand First Leader and Member of Parliament for Northland Rt Hon Winston Peters.
The data speaks for itself. Lockwood Smith threw out 17 MPs in his 4 year reign. 11 of those were from the Opposition, 6 from the government. But David Carter has thrown out 14 MPs already in just half that time - and just three of them have been from the government. So, the pattern of bias is both clear, and getting stronger.
As for what it means: a Speaker who has to throw people out this often simply does not enjoy the confidence of the House. We've seen again and again how Carter's biased decisions and his support of the government promotes disorder in the House. He's a rotten, biased Speaker, and he should go.
