The Malawi leader was speaking in Lilongwe on Sunday on his return from the Republic of South Africa where he attended the BRICS Summit.
President Mutharika said it is sad to note that Malawians are good at spreading lies and oppressing each other.
Recently, President Professor Mutharika was appointed Global Fund champion whose duty was to raise money for next year's gathering.
The Malawi leader said it is sad that some individuals went to Geneva and reported that President Mutharika should not be entrusted with the Global Fund championship.
“Two individuals by the name of Gift Trapence and Timothy Mtambo are behind this. It is sad that Malawians have reached this level,” President Mutharika wondered.
He pointed out that despite such accusations from the two individuals, the Global Fund is a voluntary work.
However, commenting on the BRICS summit the President said Malawi will benefit a lot from BRICS in terms of infrastructure development and power sector.
Malawi is expected to benefit from the bloc through the New Development Bank from a US$34 billion fund.
Malawi is from next week set to apply to the bank to bankroll infrastructure projects.
