The opposition leader has meanwhile accused the ruling MMD of creating an impression that the elections will not be held.
Mr Sata said this at a Press briefing at the party secretariat in Lusaka Friday.
He alleged that ruling MMD parliamentarians will discuss the possibility to amend some clauses in the national constitution to form a government of national unity when parliamentary sessions resume.
Mr. Sata dismissed assertions that he is sick and can not contest the forth coming presidential elections following a heart attack he suffered early in April, 2008.
He has declared himself fit and healthy for the elections.
And PF spokesperson Given Lubinda said the party is shocked at the conduct of senior party officials in the ruling MMD who he alleged commenced the campaigns before the late President Mwanawasa was put to rest.
He added that the MMD should have emulated his party that contributed to the amiable environment that prevailed in the country until the late Dr Mwanawasa was put to rest.
Mr. Lubinda challenged Dr. Rodger Chongwe to disclose the credibility of his qualifications.
He said Dr. Chongwe is not qualified to comment on people’s health condition as he is not a qualified medical doctor but instead has an honorary doctorate.
Mr. Lubinda accused Dr. Chongwe of job seeking from Mr. Banda who stands a chance of being elected as republican president in the fourth coming presidential by elections.
The PF spokesperson said this in reiterration to Dr Chongwe’s reported allegations Mr Sata is sick and cannot run for presidency
He also said that PF has qualified membership to deal with the affairs of the party and the country once voted into power.
And PF member Dr. Joseph Katema who read Mr. Sata’s medical report also declared the PF leader as fit and health to overcome the stress of campaigns and presidential office if voted into power.
Dr. Katema said Mr. Sata had suffered limited damage to the heart muscle following his quick evacuation to South Africa for medical treatment by the government.
The fourth coming by-election which is expected to take place in November has been necessited following the death of republican president Levy Mwanaweasa who died on the 19th of August in Paris France and was buried at Embassy park in Lusaka on 3rd September.
