Zimbabwe's opposition says talks on forming a cabinet with President Robert Mugabe's party are deadlocked over all key ministries.
The opposition MDC and Mr Mugabe's ZANU-PF have been in talks since an outline power-sharing deal on 15 September to end a political crisis that worsened after a disputed election and which has accelerated Zimbabwe's economic collapse.
The two sides have been unable to agree on sharing cabinet posts, but ZANU-PF said at the weekend the dispute now centred on the finance and home affairs ministries.
'The MDC dismisses ZANU-PF claims that only two cabinet posts are yet to be resolved,' the opposition said in a statement.
It called for help from the southern African regional grouping SADC and the African Union.
The power-sharing deal was brokered by former South African President Thabo Mbeki, who remains as mediator despite being ousted as president.
The opposition said there had been no contact between the parties since talks on Saturday between Mr Mugabe, Morgan Tsvangirai and Arthur Mutambara, who heads a breakaway MDC faction.
'Considering the fact that it is now exactly 21 days after the signing of the global agreement, the cabinet deadlock calls for the urgent help and assistance from SADC and AU as guarantors of the deal to unfreeze the impasse,' the MDC said.
Under the outline agreement, Mr Mugabe will retain the presidency and chair the cabinet, while Mr Tsvangirai heads a council of ministers supervising the cabinet.
