Parliament resembles a sharks' tank at times. When the Opposition scents blood on the Government benches it becomes merciless. It sensed some time ago that Labour MP Clare Curran was not up to the tasks of a minister and after her stumbling, bumbling non-answer to a question from National's Melissa Lee in the House on Wednesday, the whole country could see she was not up to it.
Her resignation announced yesterday must be a relief to her as well as the rest of the Government, though it does not reflect well on her party. Labour ministers are chosen by caucus vote. Curran's demise leaves the question, how many others in the Beehive are not really ministerial material? Her resignation will certainly encourage the sharks to look for more, as they should. It is their constitutional task to probe a government for weaknesses and keep its performance up to the mark.
Curran was a lowly ranked minister in the Cabinet before she was demoted to a seat outside the room over a second failure to properly record and account for meetings with people of interest to her in the portfolios she held. Her failings are of less public importance than they way they were handled by those holding much more power than she had.
When the Prime Minister dropped her from the Cabinet there were many who wondered why Curran was still a minister in any capacity. That view has been vindicated by the events of last week, when Curran could not form a coherent sentence in response to Lee's question about her use of her personal email on public matters.
Jacinda Ardern's judgment can fairly be question in the light of events. It is seldom easy to fire people no matter how necessary, but it comes with the responsibilities Ardern has been given.
