UPND Deputy Spokesman Edwin Lifwekelo has re-joined the Patriotic Front.
Mr Lifwekelo made the move to the PF along with some Kabwata UPND Constituency officials.
The receiving ceremony was held at Chrismar Hotel in Lusaka.
The defectors were received by PF Member of the Central Committee and Chairperson for Elections Jean Kapata.
Mr Lifwekelo was one of the founder members of PF and its first Secretary General in 2001 but he left the party after he fell out with late Michael Sata.
