A member of the Defence Strategic Review  is offering his resignation to the new minister, and thinks all political appointees should do the same.

Judith Collins became Defence Minister this morning, and Sir Don McKinnon has already written to her.

He says he was appointed by a Labour Minister, and every minister should be entitled to appoint someone different if they choose.

"One, it's the right thig to do, secondly, it's a courtesy to do it. And thirdly, if you think you're brilliant in the job- convince the Minister who's now in charge of you and the person you report to."
