ACT parliamentary leader John Boscawen on Saturday made a surprise announcement that he will be retiring from Parliament following the November election.
Mr Boscawen has been a Member of Parliament for the past three years, and held the positions of Minister of Consumer Affairs and Associate Minister of Commerce. He became ACT's deputy leader last year.
He says he will now put his family first, and spend more time with them.
However, he says he will still continue to stand as ACT's candidate in the Tamaki electorate, in an attempt to help ACT win as many party votes as possible.
ACT's board will meet next Saturday to determine how Mr Boscawen's retirement will affect the party list.
