During a live progamme on Radio Mano on Saturday, GBM said he was ready to serve in cabinet if presidents Sata offered him a position.
Mr Mwamba however denied commenting of the impasse between President and Chitimukulu the designate Henry Kanyanta Sosala.
He added that President Sata will decide when to recognize Henry Kanyanta Sosala as paramount Chief Chitimukulu at an appropriate time.
But on Monday, 23rd December, 2013, PF Kasama Central Member of Parliament, Geoffrey Bwalya Mwamba stated that his decision to step down as Defence Minister follows an ultimatum given to him by the president over Chitimukulu designate, Henry Kanyanta Sosala.
Mr. Mwamba charged that he will remain a Member of Parliament for Kasama Central.
