President Edgar Lungu has challenged those alleging that the August 11 General election will be rigged to provide evidence.
President Lungu says some opposition leaders should not use speculations of rigging as an excuse if they lose election.
The President also says persistent allegations of rigging shows that the opposition leaders are not ready for the election.
He labelled those with unfounded allegations of election rigging as cry babies.
President Lungu was speaking in an interview with journalist at Kenneth Kaunda International Airport enroute to Uganda.
Meanwhile, Phoebe Sakala reports from Kampala that President Lungu will be in Uganda, to attend the 40th anniversary of the Entebbe operation.
This was a successful counter-terrorist hostage-rescue mission, carried out by the Israel Defense Forces, at Entebbe Airport in Uganda.
This hostage rescue happened on July 4, 1976, a week after an Air France plane with 248 passengers had been hijacked by Pro-Palestinian militants.
President Lungu, who has been invited by President Yoweri Museveni, will be among 6 other heads of state, who include Israeli Prime Minister, Benjamin Netanyau.
Zambia’s High Commissioner to Tanzania, judith kapijimpanga, who is also accredited to Uganda, has confirmed this in an interview with ZNBC in Uganda.
According to a programme released in Kampala, the heads of state will later hold a closed door summit on counter-terrorism, and later issue a communiqué, after the commemorations.
The whole programme is expected to end at 17 hours.
President LUNGU is later expected to return to Zambia, the same day.
