Opposition leader Chishimba Kambwili has accused President Edgar Lungu of using presidential planes to courier illegal drugs with Valden Findlay.
At a media briefing on Monday, Kambwili challenged president Lungu to state the nature of business he is involved in with Findlay, a drug dealer.
Kambwili wondered why whenever Lungu emerges from the door of the presidential plane, the next person to emerge is Findlay.
Kambwili asked Lungu to deny reports that he and Findlay are using the presidential plane to supply cocaine and other illegal substances.
He wondered why the president could be associating himself with a well known drug dealer and partner of international drug-lord Goswami.
Kambwili appealed to the USA to come to Zambia and arrest Findlay.
