MDC-T Bulawayo provincial chairman and former Cabinet minister Mr Gorden Moyo yesterday resigned from his post in the Morgan Tsvangirai-led faction citing leadership failure and lack of direction.
Mr Moyo said the leadership, which had failed to handle the outcome of the 2013 poll, was busy chasing lizards when crocodiles were against it.
His resignation comes as problems mounted for Mr Tsvangirai, with the party's Manicaland provincial youth assembly announcing yesterday that its members were defecting en mass to the Renewal Team faction led by secretary-general Mr Tendai Biti.
The Zimbabwe National Student Union, a long time ally of Mr Tsvangirai, also announced yesterday that it was transferring its allegiance to Mr Biti's faction.
Mr Moyo, who was Minister of State Enterprises in the doomed inclusive Government, said at a Press conference in Bulawayo that he would remain an ordinary party member and Member of Parliament for Makokoba.
He said the infighting rocking the opposition was a symptom of leadership failure after the party lost last year's harmonised elections to Zanu-PF.
Mr Moyo, once believed to be a close ally of Tsvangirai due to his links to donors, said he chose to resign "than be part of a failed leadership".
"On this day, the 13th of June 2014, I, Gorden Moyo, am stepping down from the office of the chair of Bulawayo province with immediate effect," he said. "An angel of darkness has visited our party. We have been raped by a demon and become like the Tower of Babel - full of confusion."
Mr Moyo said he submitted his resignation letter to the secretaries- general of both factions.
"I can't pretend there is one MDC and so for avoidance of doubt I wrote to both of them," he said.
The former civic society activist once labelled a "mafikizolo" after he dribbled his way into party leadership ahead of founder members during the 2010 congress, said the MDC-T had betrayed the people of Zimbabwe and lost relevance in the country's politics.
"We are pushing a self-destruction button. Given circumstances in the current context, I find it difficult to operate in such an environment where we fight friends and not foes."
Mr Moyo said the MDC-T's latest split was a replica of the 2005 one which gave birth to a faction led by Professor Welshman Ncube.
"We failed to dislodge Zanu-PF as a united MDC, what more as a fragmented party?" said Mr Moyo.
National organising secretary Mr Nelson Chamisa said Mr Moyo's departure was not a surprise given that "he only joined the party just before the formation of the inclusive Government".
"That's the normal life of a party," he said. "People choose when to serve and when not to serve. When the vehicle is moving some people jump out to safety at the slightest bump, but we will get to the destination. It's a comfortable development. It's his democratic right."
The party's Manicaland youth assembly members led by Mr Dennis Simango said in a statement yesterday that they were parting ways with Mr Tsvangirai because of his "dictatorial tendencies".
"We, the undersigned MDC provincial youth executive of Manicaland have met today (yesterday) and unanimously agreed and resolved to among other things to endorse the Mandel council resolutions in their entirety," reads part of the statement.
"To officially join our colleagues in the MDC Renewal Team in pursuit of democratic goals and dissociate ourselves from MDC Tsvangirai."
Zinasu president Gilbert Mutubuki said in a statement yesterday that Mr Tsvangirai could no longer inspire students.
"It is time to part ways and start a fresh political ground for the students," reads the statement. "Violence is taking place at each and every rally and some party leaders aligned to Tsvangirai are unleashing youths to assault other party leaders who differ with them."
