Carr welcomed, but has got it wrong on Afghanistan: Greens

Australian Greens Leader Bob Brown has welcomed Bob Carr's nomination for the Foreign Ministry but says he is wrong to want Australia's troops kept in Afghanistan.

"As a new broom, Mr Carr ought to begin by extracting our troops, to bringing them home from the mire in Afghanistan this year," Senator Brown said.

"I look forward to having a foreign minister in the Senate and congratulate the other new appointees of Prime Minister Gillard.

"The elevation of small business to cabinet is a good call," Senator Brown said.
