MMD vice-president for administration Brian Chituwo has insisted that the expulsion of party national secretary Richard Kachingwe was unconstitutional as fresh information emerges that some national executive committee (NEC) officials and Members of Parliament (MPs) will soon ditch the party.

On Saturday last week, Dr Chituwo, who was flanked by MMD national women's chairperson Catherine Namugala, said at a media briefing that NEC would soon review the matter and decide the way forward.

He, however, noted that while the expulsion of Major Kachingwe was wrong, the invalidation of the election of party president Nevers Mumba was equally not in line with the party constitution.

In an interview yesterday, Dr Chituwo maintained his earlier position which he said was in line with the party constitution.

Vubwi MP Eustarkio Kazonga refused to make any comment regarding the current party affairs.

Meanwhile, fresh information has emerged that some NEC officials and MPs would soon ditch the former ruling party because of factors that hinge on continued internal bickering.

According to sources, MMD parliamentarians felt that they were highly levied in terms of monthly contributions.

The sources said the MPs were reportedly frustrated as they were contributing towards a party whose leadership was abrogating the constitution.

"There is a sense of massive resignations from top NEC officials and MPs wanting to resign because you have seen there are leadership cracks currently happening in MMD and if this continues, it will heavily cost the party," the sources said.

The sources said several MMD cadres in Lusaka and other areas were also contemplating to defect because of alleged failure by Dr Mumba to reorganise the party.

"If you have noticed, there are two factions in MMD, there is a group supporting Dr Mumba while others are against his leadership and want either Mr Felix Mutati or Dr Situmbeko Musokotwane to lead the party now," the sources said.
