I'd missed this news that the 'Kariba Draft constitution' was to have a round of public consultation and a vote until an email arrived from a Zimbabwean e-list. For further details see: www.sokwanele.com/zimbabweconstitution

Which cites:
Zimbabweans will be asked to vote on a new draft constitution when it is finally ready. The public outreach programme, intended to gather the views of the people, is scheduled to start early in the new year.
Missing is any date for the vote. Just a reminder a new constitution drafted by ZANU-PF under President Mugabe was rejected in a vote a few years ago, much to his surprise and anger.

No-one I expect in Zimbabwe is under any illusions how the 'public consultation' will go, let alone any future vote.
