BROWN RESIGNS AS GREENS LEADER
Bob Brown has resigned as leader of the Australian Greens and will also resign from the Senate.
After 16 years of service, Mr Brown made the announcement to Greens party room colleagues at 10am this morning.
"I am sad to leave but happy to go," Senator Brown said in a statement.
"It is good knowing that the Greens have such a depth of talent and experience lined up for leadership - I could only dream about that a decade ago."
He thanked his nine colleagues and the 1.7 million voters who supported the Greens in 2010.
"They have made each Green year in this parliament better than the year before - though the best is yet to come," he said.
Senator Brown advised the governor-general, Prime Minister Julia Gillard and the leader of the Tasmanian Greens of his decision.
Senator Brown will also resign from parliament when his Tasmanian replacement is available in June.
"I look forward to fresh green pursuits including writing, photography, music, occasional talks, bushwalking, and getting out with Paul to see Miranda Gibson, who has been perched for 120 days 60 metres high, in defence of a giant tree facing destruction in central Tasmania," the 67-year-old senator said.
The party's deputy leader Christine Milne tweeted that she had been elected leader: "I'm honoured & excited to have been elected leader of the @GreensMPs to build on the great legacy of @SenatorBobBrown."
Senator Milne on Friday paid tribute to her predecessor's "extraordinary leadership".
"For 25 years, Bob has been an inspiration to millions of Australians and a great force for good in our country," she said in a statement.
"Under Bob's wise leadership, the Greens have grown into the undisputed third force in Australian politics."
