UPND president HAKAINDE HICHILEMA has called on Zambians to step up efforts aimed at pressing government to release the final draft constitution and the subsequent enactment of the new constitution. Mr HHICHILEMA says the UPND alone can NOT manage to compel the ruling party to give Zambians a constitution. He said this is why UPND is working with other organisations under the Grand Coalition. Mr HICHILEMA said this at a press briefing in Lusaka day where about ten people defected from various parties to join the UPND. President MICHAEL SATA yesterday directed Ministers and senior government officials to concentrate on their co- duties and ignore people making demands for a new constitution. The President who has on many occasions reminded his ministers and government officials to ignore demands for a new constitution said the country already has a functional constitution. And Mr HICHILEMA said the economy will continue to weaken in the wake of the recent one billion US dollar sovereign debt.
