Harare: Zimbabwean President Robert Mugabe has said that he will go ahead and form a cabinet if opposition leader Morgan Tsvangirai does not sign a power-sharing deal on Thursday, state media reported.

The state-run Herald newspaper quoted Mugabe as saying "we will certainly put together a cabinet" if MDC leader Tsvangirai does not sign an agreement. South African President Thabo Mbeki is set to arrive in Zimbabwe on Thursday to continue his mediation efforts.
