The Green Party is in turmoil following Metiria's Turei's unwillingness to stand down from leadership.

Two senior MPs have quit the Green Party as Turei did not stand down as they wanted her to.

Co-leader James Shaw said last night he wanted to go further and expel the two MPs from the Green party.

The two MPs exiting the caucus are Kennedy Graham and David Clendon.

The disagreement started over Ms Turei's admission she had lied to welfare authorities twenty years ago.
