BLANTYRE, June 23 (Reuters) - Malawians voted on Tuesday in
a re-run of a discredited presidential election seen as a test
of Africa's ability to tackle ballot fraud, but the country's
president said reports of violence called the integrity of the
contest into question.
Malawi's judiciary infuriated President Peter Mutharika, in
power since 2014, when it overturned his narrow victory in
February over "systematic and grave" irregularities.
His disputed win also sparked months of anti-government
protests, a rare sight in Malawi. Last week hundreds of lawyers
also protested when Mutharika tried to retire Chief Justice
Andrew Nyirenda, forcing the president to back down.
The supreme court upheld the annulment of the election win
last month, a decision that Mutharika, 79, called a "coup" in a
campaign rally on Saturday in the northern district of Rumphi.
After voting at a school in the tea farming district of
Thyolo, southern Malawi, Mutharika decried what he described as
violence in opposition strongholds in central Malawi.
"It is very sad. Our secretary general has been beaten up,"
he said. "Those causing the violence are desperate. How then
will the election be credible?"
There was no independent confirmation of the alleged unrest,
although the electoral commission said it had received reports
of violence.
After voting in the capital, Lilongwe, Chakwera told his
supporters: "There is no reason really to resort to violence ...
The vote itself is the fight we need." He added that he believed
the election would be fair this time.
The judiciary's ruling echoed one by a Kenyan court in 2017,
which cancelled President Uhuru Kenyatta's election win. Both
were remarkable on a continent in which judges often serve as a
rubber stamp to executive power.
The vote looks too close to call. Malawi has since ditched
its "first-past-the-post" system so the winner has to get more
than 50%.
'I PRAY MY VOTE WILL COUNT'
About half of Malawi's predominantly farming population live
in poverty. Lying on a lake at the southern tip of the Great
Rift Valley, Malawi mostly exports tobacco and tea.
In the May 2019 poll, Mutharika got 38.57%, 3 percentage
points more than opposition leader Lazarus Chakwera, and less
than 10 points ahead of a third candidate, Deputy President
Saulos Chilima.
The 47-year-old Chilima has now backed Chakwera, 64, which
would give them a majority if they can combine their previous
votes.
Mutharika's Democratic Progressive Party is in an alliance
with the southern African nation's ex-ruling party, the United
Democratic Front, which got less than 5% last time.
"I'm glad to vote again. This I pray, that my vote will
count," said Bernado Simbi, 36, a domestic security guard after
voting for Mutharika in a school near Chileka Airport, north of
the commercial capital Blantyre.
Mutharika, a former law professor, has revamped Malawi's
roads and boosted electricity while also taming inflation. Yet
critics accuse him of doing little to tackle corruption.
"The government has lost the anti-corruption fight (and) the
opposition has taken advantage," said Happy Kayuni, political
science lecturer at Malawi University.
Chakwera has made graft a central pillar of his campaigns.
COVID-19 restrictions will make it tricky for foreign
observers, who did not detect fraud last time.
