Zimbabweans voted on Saturday in a referendum expected to endorse a new constitution that would trim presidential powers and pave the way for an election to decide whether Robert Mugabe extends his three-decade rule.
Mugabe, Africa's oldest president at 89, has ruled the former British colony since independence in 1980 and has been accused of waging violent crackdowns on the opposition and weakening state institutions like the cabinet and parliament.
The new constitution would set a maximum two five-year terms for the president, starting with the next election, expected in the second half of this year. But the limit will not apply retroactively, so Mugabe could rule for another two terms.
