HARARE (Reuters) - Zimbabwe President Robert Mugabe signed a new constitution into law on Wednesday, replacing a 33-year-old document forged in the dying days of British colonial rule and paving the way for an election later this year.
Approved overwhelmingly in a referendum in March, the constitution clips the powers of the president and imposes a two-term limit. However, it does not apply retroactively so the 89-year-old Mugabe technically could extend his three decades in office by another 10 years.
A beaming Mugabe, flanked by Prime Minister Morgan Tsvangirai, his main political rival, and Deputy President Joice Mujuru signed multiple copies of the charter at State House in the capital to cheers and applause from aides.
The constitution was rewritten under terms of a power-sharing deal between Mugabe and Tsvangirai after elections in 2008 marred by violence.
The five-year coalition government formed under the same agreement expires on June 29, and parliamentary and presidential elections should follow within 90 days of that date.
However, many obstacles remain, not least finding the estimated $130 million needed to pay for the election and reaching agreement on outside monitors.
Harare has turned down offers of United Nations or donor assistance and Mugabe accused some in the 15-nation Southern African Development Community (SADC), which has been mediating in the crisis, of trying to impose their will.
"We rejected this," he told reporters after the signing ceremony, adding that any vote would be fair. "We will ensure that there won't be any violence, that there won't be any rigging."
Mugabe made no mention of an election date but Tsvangirai later told reporters it would be later rather than sooner because of the need to amend electoral laws and allow the 30-day registration period for new voters mandated in the constitution.
State media said on Wednesday that Mugabe was pressing for a vote before July although his rivals wanted it delayed to allow for the opening up of broadcast media, registration of new voters and reform of the military to ensure it stays out of politics.
