And Dr. Mumba has described the warm reception he received by Eastern Province party officials as humbling.
Dr. Mumba has advised party members to ensure that they stand on love for one another and to be truthful all the time as lies and hatred will destroy the party.
Dr. Mumba says for the party to get back to its past glory, its members needs to work with one another as well as for one another.
Dr. Mumba says giving the MMD a chance to reclaim power within the shortest period of time is the only hope for Zambians because the people know what the MMD can do for them.
On the pessimists saying the former ruling party is finished, Dr. Mumba has urged members to ignore such people as leadership is not given by man but God.
He says as long as the party remains intact, MMD stands a better chance of scooping the 2016 elections compared to other political parties as it is the biggest party in the country with a presence in all provinces which other parties including the ruling PF cannot boast of.
He says when the MMD was voted out of office in 2011, it left a country with sound economic policies and stable currency as well as an agriculture policy that was putting not only food on the tables of poor people but some extra money for school fees as well.
