The Greens are disappointed with the provisional result of the Western Australian Senate count.

Scrutineers have identified the result may have come down to a 14 vote margin and will likely require a recount before the final result is known.

Senator Ludlam has thanked the 124,000 people who voted Green in WA, and the Western Australian and national campaign teams for their work during the election campaign.

Dear Green Friends --

This morning I resigned as Leader of the Australian Greens. I will leave the Senate in June when the Tasmanian Greens nominate a replacement Senator. The time has come.

I wanted to immediately thank you for your support, enthusiasm and direct involvement in Green politics on my watch. I can never forget or adequately repay the personal encouragement I have received over so many years from you, my family, friends, colleagues, work mates, party workers, voters and supporters.

At today's hearing into Tasmanian Senator Bob Brown's bill to improve community consultation into towers built by telecommunications carriers, the Local Government Association's Adrian Beresford-Wylie said local government wanted the right to accept or reject proposals.

"The distress caused by towers being foisted on communities with little notice will not be met by the new code of practice the industry now proposes," Senator Brown said.

Australian Greens Leader Bob Brown spoke to reporters in Canberra today about his visit to Queensland, Tony Abbott's lack of confidence in winning a no-confidence motion, and the Greens getting on with the hard work of good governance.

"If you're fed up with the old parties, vote Green," Senator Brown said.

Coalition frontbencher Senator George Brandis has bowed to Greens' demands (since December) and has stood down from a signal case before the Senate's powerful Privileges Committee.

Australian Greens Leader Bob Brown spoke to press gallery journalists this evening about Senator Brandis' secret "recusal" from the Senate's powerful privileges committee, only recently revealed in a letter to Senator Brown's and Deputy Leader Christine Milne's legal counsel.

Australian Greens Leader Bob Brown has called on Liberal powerbroker George Brandis to remove himself, or be removed, from the Senate Privileges Committee because he has pre-judged the question of the integrity of Greens Senators Brown and Milne.

"I have reminded the Senate that the Committee of Privileges has the power to recommend jail sentences of six months for Senators. It is parallel to our courts, must apply standards of justice like those of the courts and its decisions are appellable to the courts. Senator Brandis must go," Senator Brown said in Canberra today.

Australian Greens Leader Bob Brown welcomed the release today of the report by the Expert Panel on Constitutional Recognition of Local Government.

"The Gillard government and the Opposition should get behind this important and needed constitutional reform," Senator Brown said.

"The panel's outcome is the result of the process that stemmed from the agreement the Greens signed with Labor on 1 September 2010."
