Malawi’s president Peter Mutharika says he will contest a court ruling that overturned his election last May.
Mr Mutharika, Malawi’s president since 2014, won the election with a 38.5% share of the vote. Opposition party leader Lazarus Chakwera came second with 35.41%
On Monday, judges annulled the vote citing irregularities and ordered a new election within 150 days.
There have been regular anti-government protests since the election.
Mr Mutharika said he will lodge an appeal against the ruling by five judges.
This was the first time a court had annulled an election in Malawi, creating further uncertainty in the southern African state.
Presidential spokesman Mgeme Kalirani said the ruling “cannot be allowed to stand … it will create a lot of problems in the country’s jurisprudence.
“It is a great miscarriage of justice,” he added in a statement.
