LABOR'S NSW general secretary Karl Bitar will be rubber-stamped into Labor's top campaign job when the national executive meets on Friday.

It is understood Mr Bitar, pictured, has the support of the Prime Minister and all the factions to be endorsed as Labor's national secretary. He would replace Tim Gartrell, who helped mastermind Kevin Rudd's winning election pitch in November.

Gartrell, in the job for five years and the national office for 10, will join a private sector research group, having told friends he was nearing burnout.

Mr Bitar, 37, contacted the 25 members of Labor's most powerful body to present his case for the job as Labor's top national campaign manager.

The NSW Labor chief, accused of masterminding the downfall of former NSW premier Morris Iemma, is pressing his credentials as a factional uniter rather than warlord.

He has told Labor heavyweights he will no longer attend factional meetings of the right-wing, of which he was a member.

He intends to follow in the footsteps of his predecessor, who hailed from the left-wing but became non-aligned.

Mr Bitar has pledged to focus on research, polling and campaigning for the party as a whole.
