Former United Party for National Development-UPND Vice President Richard Kapita has advised senior officials still serving under UPND President Hakainde Hichilema to take courage and resign because the opposition party is destined for doom.
Mr Kapita said there is no need for the senior UPND officials to cling on to a political party that will never form government.
He has advised senior UPND officials to instead join the Patriotic Front under its visionary leader Edgar Chagwa Lungu.
Mr Kapita said after his defection to the PF, North Western province has seen various development projects being initiated and implemented for the good of the people.
He was speaking in Mulobezi in Western Province when President Lungu addressed a campaign meeting to drum up support for PF candidate Patricia Mulasikwanda Mambeya in the June 30 Mulobezi parliamentary by-election.
Mr Kapita claimed that the UPND and its leadership have gone on a smear campaign to malign him in the social media.
He said because of this negative campaign following his defection from the UPND, he is now compelled to seek legal redress.
Meanwhile, President Edgar Lungu has lashed out at critics who have been accusing the PF of doing nothing to improve the operations of the Mulobezi railway line.
President Lungu is concerned at the level of vandalism on the Mulobezi railway line saying it was not good as the rail line is for public good.
The president told the campaign meeting the PF has since assuming government implemented a robust programme of action to revatilise the once ailing operations of the Mulobezi railway.
He said previously it used to take one week for people to travel from Mulobezi to Livingstone.
President Lungu said there is now decency as people are no longer being transported with livestock as the case was before.
