President Sata said the residents will never experience development if the opposition members of parliament continue to represent them.
He was campaigning for PF candidate Lawrence Evans ahead of the February 28th by-elections which are being contested by UPND, MMD and many other opposition parties.
In recent months Zambia has experienced an unprecedented number of by-elections for parliamentary seats, which are usually triggered by defections of MPs to the ruling party as well as electoral tribunal petitions.
President Sata said Southern Province has lagged behind in development because of being identified with the opposition.
He said the PF has honoured its promises and created over 50,000 jobs. Former MMD member Daniel Munkombwe also said opposition MPS are held as hostages by heir parties to which they belong.
The trip to Livingstone represents the first outing for President Sata in a long time, following months of confinement to State House allegedly due to his deteriorating health. His attendance of the rally has been regarded as an act of defiance from his physicians who have recommended enough rest and reduction in travels to avoid worsening the problem.
