HARARE, Zimbabwe - Zimbabwe's electoral panel on Saturday declared that longtime President Robert Mugabe had won re-election by a landslide, a result that could exacerbate tensions in the country, where the 89-year-old's chief rival and former coalition partner has accused him of poll-rigging.
Mugabe seemed set to strengthen his hold over Zimbabwe after the state Election Commission said his party won 158 of the 210 parliament seats. That gives it a two-thirds majority in the legislature - enabling it to amend a recently approved constitution that provides for democratic reforms.
Challenger Morgan Tsvangirai's party, which had gambled that a high turnout in its favor would overcome any alleged fraud in the vote, captured 50 seats and two went to independent candidates.
According to the results, Mugabe won 61 percent of the vote, compared to 33 percent for Tsvangirai, who had been prime minister in a tense power-sharing deal with the president.
Officially, Mugabe, who has been in power for 33 years, gets another five-year term in office.
Tsvangirai rejected the results as fraudulent and called for fresh elections.
He urged a peaceful response to the alleged massive rigging by Mugabe's ZANU-PF party, which has the muscle of the security forces to deter any groundswell of street protests.
