Malawi’s President Peter Mutharika is leading his rivals after the counting of 75% of votes in Tuesday’s fiercely contested election.
Partial results released by the Electoral Commission show the 78-year-old Mr Mutharika has so far obtained 40% of votes cast.
This compared with the 35% of main opposition leader Lazarus Chakwera, and the 18% of Vice President Saulos Chilima, according to the partial results.
Mr Chakwera warned on Wednesday of attempts to rig the Poll, saying counting by his Malawi Congress Party (MCP) puts him in the lead.
Malawi has a winner-takes-all system, with no run-off election.
Corruption was a major issue during the campaign, with the opposition arguing that it had worsened since Mr Mutharika became President five years ago.
