Patriotic Front (PF) president Michael Sata says Zambians should understand that the PF and UPND are different parties with just a working relationship.
Sata was quoted by a local radio, HOT FM, saying that he has no problem with UPND president Hakainde Hichilema declaring himself the best candidate for 2011.
He said as leader of the other party, Hichilema is at libertyto camapign for himself.
Sata said it is good that Hichilema has declared himself now instead of doing so at the last minutte.
Sata said that he has no quarel with that but wondered if that is the reality on the ground.
He was reacting to a news article published in the Times of Zambia on Monday where Hichilema is quoted saying he is the better candidate for 2011.
