The PF has accused UPND of scheming a desperate maneuver to create circumstances for advancing a government of national unity.
PF Deputy Spokesperson Frank Bwalya says the UPND seeks to find excuses not to concede a possible defeat in the August 11 general election.
Mr. Bwalya said this is why the opposition party has been pulling one desperate move after another citing the fracas that led to the shooting of one their members on Friday.
Speaking during a press briefing in Lusaka, Mr Bwalya accused UPND of using the shooting incident to elicit political mileage and cheap public sympathy.
And Mr. Bwalya has declared that a government of national unity will not happen because Zambians will vote decisively for the PF to retain power.
He has also dismissed allegations of possible vote rigging.
Mr. Bwalya said the UPND which has sensed defeat in the August 11, election is scouting for excuses.
But UPND Spokesperson Charles Kakoma says his party has no intention of forming a government of national unity with the PF.
Mr. Kakoma said UPND has enough political support to win the polls.
He told ZNBC news that his party has gained enough grounds to emerge victorious.
