Zanu PF politburo members were until late last night still locked in what insiders described as an explosive extraordinary meeting to scrutinise the draft constitution.
The meeting is likely to end late and some issues have actually been postponed to a later date since they are going through it (the draft constitution) page by page, said the source.
The party is currently believed to be divided into three groups over the draft and these are; an anti-draft group led by Jonathan Moyo, a pro-draft group led by Defence minister Emmerson Mnangagwa and Legal Affairs minister Patrick Chinamasa and a third group led by Vice-President Joice Mujuru which is believed to be neutral.
Sources said the party gurus had failed to find common ground on issues to do with executive and presidential powers and Attorney-Generals powers.
Yesterdays meeting was a follow up to another politburo meeting held in Harare on Wednesday where Didymus Mutasa, secretary for administration, presented his provincial outreach report on the contentious issue of District Coordinating Commitees (DCC) that were disbanded recently.
The party claimed that the DCC elections were causing divisions.
The politburo was also expected to tackle the issue pertaining to their Chief Whip Joram Gumbo who was accused of dissent by voicing that the disbanding of DCCs was not welcome.
