After the last couple of days, the message that the Prime Minister is on the phone will now inevitably send at least a brief twinge of nervousness up and down the spine of John Key's Cabinet colleagues.
His surprise phone calls to Kate Wilkinson and Phil Heatley on Monday night and yesterday morning respectively were a "From John" letter rather than a "Dear John" letter. But the message was exactly the same.
The two now-former ministers were told they had made a great contribution to Key's government over the past four years. But they were no longer wanted.
In wielding the axe, Key is not yet uttering the demented "Here's Johnny" cry of Jack Nicholson's character in The Shining.
But he is nothing short of ruthless. He was not called the Smiling Assassin for nothing by fellow dealers during his job-cutting at Merrill Lynch's foreign exchange operations.
Regardless, the two now-former ministers sit atop the political scrap heap.
Their fate is unprecedented in recent New Zealand political history. Cabinet ministers are usually demoted to lesser portfolios when their competence has been questioned - rather than being dumped altogether.
Wilkinson and Heatley may well also ask how Nick Smith's return from 10 months' penance refreshes Key's line-up. They will ask why they are being singled out when Hekia Parata is not.
The difference is that Parata has had just a year in the Education portfolio. Wilkinson and Heatley have had four years to make a difference.
Key is said to be looking for more energy and urgency this year. Neither Wilkinson nor Heatley were seen as offering that. They were expendable.
Their sacking reflects Key's latent power as leader, and some rather pressing political realities.
Key needed far more oomph in Heatley's Housing portfolio. Wilkinson is seen in the Beehive as lacklustre and politically accident prone.
It may be brutal. It may set a precedent in terms of ministerial competence. But that is no bad thing.By John Armstrong Email John
