David Lewis has resigned

For those of you who don't know, David Lewis is the PM's press secretary. Well, he was her press secretary but he has resigned due to family circumstances. He's only been in the job about a year or so. Perhaps Helen Clark and Heather Simpson can job share the position. They are both well qualified to do so - both understand the media, both lie well, both can spin, and both can speak on behalf of the Prime Minister with authority, and know how she thinks.

Of course H1 and H2 would never resign due to family circumstances, would they?

Who do you think would replace Lewis?
