Britain would back proposals for a full arms embargo on Zimbabwe following revelations that a Chinese ship laden with weapons had attempted to deliver its cargo to the landlocked country, according to the dpa.
"Because of what has happened in South Africa, where there is an arms shipment trying to get to Zimbabwe, we will promote proposals for an embargo on all arms to Zimbabwe," Brown said.
The Chinese vessel, the An Yue Jiang, left the South African port of Durban after dockworkers there refused to unload the cargo of AK-47 rifles, mortar bombs and rocket-propelled grenades.
After being faced with a similar response by neighbouring African countries the vessel was reported Tuesday to be sailing towards Angola, and possibly "heading for home."
Zimbabwe's failure to announce the result of last month' elections was "completely unacceptable," Brown told members of parliament.
"I call on the whole world to express its view that this is completely unacceptable to the whole of the international community," said Brown.
He urged African Union (AU) observers and international monitors to make their views known about the "unfairness of this election."
