"The hollowing out of the Labour Party continues. Soon Shearer and his sponsors will have the party to themselves."Featured comment
Labour MP Charles Chauvel says he will resign his seat on March 11.
The one-time party high flyer says he has accepted a position with the United Nations in New York (workplace of former Prime Minister Helen Clark), advising on parliamentary development and democratic governance.
Mr Chauvel was pegged by media as a member of "Camp Cunlifee" during the recent Labour leadership spat.
As the incumbent David Shearer consolidated his position in February, easily winning a leadership vote, Mr Chauvel found himself on the outer.
A former Minter Ellison partner, Mr Chauvel entered parliament as a list MP in 2006 as a list MP.
He has served as Labour's justice spokesman since February 2011 and as the shadow atorney-general and Labour's arts, culture and heritage spokesman since December 2011.
For the past two years, the openly gay Mr Chauvel has also been a member of the United Nations' Global Commission on HIV and the Law, a part-time position.
Former MP Carol Beaumont is next on Labour's list.
