Senior WA Green wants Di Natale to resign

A three-time co-convenor of the West Australian Greens wants Richard Di Natale to resign after his calls for a purge of leaking members.

A three-time co-convenor of the Western Australia Greens has called on Richard Di Natale to resign as leader of the federal party.

Grahame Bowland, who until recently was the WA Greens co-convenor, said he was disappointed Senator Di Natale called for a purge of members who leaked bullying complaints about failed Batman by-election candidate Alex Bhathal.

"Since Richard's appointment as federal parliamentary leader, untold cultural damage has been inflicted upon our movement," Mr Bowland posted on Facebook on Monday.
