Mr. Mwamba has since advised his brother to stop behaving like Judas Iscariot.
Speaking to QFM News in an interview, Mr Mwamba has advised his brother not to forget where he is coming.
He says family relationship is very important and anyone who forsakes his family for the love of money can never leave at peace.
Mr. Mwamba, who restrained himself from commenting further on the wild allegations made by his brother, stated that it will not be long before time judges his younger brother harshly for his reckless comments about him.
And commenting on his suspension by the Patriotic Front Northern Province executive, Mr. Mwamba said he has not received any formal letter of suspension.
He has since described his suspension as hearsay.
Meanwhile Kasama central Patriotic Front constituency Chairman Abraham Mulenga says the Northern Province executive committee is a wrong body to suspend Mr. Mwamba from the party.
Mr. Mulenga stresses that the constituency has no reason to suspend Mr. Mwamba because he is still loyal to the structures.
