The ruling PF has attributed its victory in the Kasenengwa parliamentary by election to hard work.
PF Deputy Media Director Antonio Mwanza says the PF has held the seat for the past seven years and the people in the area trust the party.
Speaking to ZNBC News in an interview, Mr Mwanza has also congratulated the new MP Sensio Banda for emerging victorious in the poll.
He said all the PF structures and President Edgar Lungu worked flat-out to ensure that the party retains the seat.
Mr Mwanza said the party will now work hard to fulfil its electoral promises to the electorate.
