Saulos Chilima, who had been Mutharika's vice president since 2014, also put up a strong challenge against Mutharika since the two parted ways in April 2018. The election was marred with controversy and claims of rigging by Mutharika's DPP. In some districts such as Nsanje and Chikwawa in the southern end of Malawi, the Malawi Electoral Commission staff managing the polls were accused of swapping the presidential results for Chakwera to be for Mutharika.
