Former National Party leader Don Brash has confirmed his successor, John Key, has talked to him about possible jobs if National wins the election, but says there has been no discussion about a plum diplomatic posting in London.

At the time Mr Key took over from Dr Brash in November 2006, there was speculation Mr Key may have promised him a future diplomatic posting in return for stepping down.

Dr Brash today said there had been a discussion when he left Parliament two months later.

"When I left Parliament John Key said to me, look if we win the election in 2008 lets talk about some of the things you might be able to do to help the country and that's as far as its gone.

"There's no suggestion of particular jobs, of particular posts, at all," he told NZPA.

"He alluded to all sorts of things. In general terms he alluded to offshore posts, to onshore posts, SOE (state-owned enterprise) boards, all sorts of things I might be able to help with, but there was nothing specific offered at all."

Dr Brash said he would consider any offer on its merits and was not prepared to rule anything out or in.

However, he was not interested in jobs that were mainly ceremonial in nature.

Speculation about the posting follows the Sunday Star-Times today reporting a National source saying Mr Key was planning to appoint Dr Brash to the role in 2009.

The newspaper said such an appointment would require career diplomat Derek Leask, who currently holds the position, to return to New Zealand early.

The job pays a salary of $130,000-$169,000 a year.

Dr Brash is currently a director of the ANZ-National bank, Hulich Wealth Management and Christchurch company Ocean Partners.
