Robert Mugabe: Zimbabwe unity deal should end next year

Zimbabwe's president has said a power-sharing deal which expires in four months' time should not be extended.

Robert Mugabe said the country should hold a referendum on a new constitution early in 2011 and then elections.

He said he was reluctant to renegotiate the unity deal as some events happening in the coalition were "foolish".

Mr Mugabe has been sharing power with rival Morgan Tsvangirai since last year, under a deal worked out after disputed 2008 elections.
