Mutharika was speaking Saturday afternoon at Kamuzu International Airport in Lilongwe on arrival from New York, USA where he attended the 74th UN General Assembly (UNGA).
There has been political tension since May 21 elections which saw Mutharika declared winner by the Malawi Electoral Commission (MEC).
Opposition Malawi Congress Party (MCP) and UTM Party disputed the results and went to court saying the polls were flaudulent and marred by irregularities.
The President said the UN will soon release a statement to help address the situation the country is currently in.
Mutharika said it was expected of him to address the UNGA on all aspects surrounding the country including the current political tension.
He said the major challenge he mentioned to the house was the political tension which is a result of some opposition parties’ failure to accept the election results.
“I explained to the assembly on how the opposition political leaders are failing to accept the elections,” he said.
Mutharika said the elections were declared free and fair by international observers who were present during the electoral process.
He said the UN observers were part of the monitoring team present in the country during the May 21 tripartite elections.
The President said apart from addressing the General Assembly on the political situation in the country, he also highlighted some of the developmental projects being implemented in the country.
“I highlighted development projects that government is implementing such as the economic development [and] community projects,” he said.
This was Mutharika’s sixth UNGA to attend and he addressed the assembly on Thursday, 26th September 2019.
