Lusaka – Zambian opposition party, the United Party for National Development, called President Edgar Lungu the weakest head of state the country had ever had, reports the Post.
UPND member of parliament Carlos Antonio accused Lungu of being too scared to call his "corrupt ministers" to order.
Antonio said Lungu was a toothless leader who had caused the country to fall on hard times.
"Lungu's docility to act on his erring ministers and party members is what is dragging this country into anarchy," Antonio was quoted as saying.
Lungu came into office last year following a snap election in January, after the death in office of president Michael Sata in October 2014.
According to reports, Lungu's administration had failed to deliver on promises made during his election campaign.
Despite the criticism from the opposition, Lungu on Monday expressed confidence that he would emerge victorious in the upcoming elections. He said he had worked hard as the country's head of state and would continue to do so.
Zambia was expected to elect its next president on August 11.
