MASVINGO, Zimbabwe (Reuters) - Zimbabwean Prime Minister Morgan Tsvangirai's MDC party on Sunday invited the African Union (AU) and another regional group to help sort out problems in its unity government with President Robert Mugabe.

Long-time rivals Mugabe and Tsvangirai of the Movement for Democratic Change (MDC) formed a unity government in February after months of wrangling but sharp differences remain over issues such as the posts of central bank governor and attorney general.

On Sunday, the MDC's National Council agreed at a meeting that the AU and the Southern African Development Community (SADC) -- which brokered the Zimbabwe power-sharing deal -- should step in to break a deadlock with Mugabe on issues still unresolved under their Global Political Agreement (GPA).

"The National Council resolved that all outstanding issues be referred to SADC and the AU as guarantors to the GPA," the MDC said in statement.
