Zimbabwe divides opinion like almost nothing else in Africa.
Mugabe blames his exclusion on a white "unholy alliance"
President Robert Mugabe has quit the Commonwealth because it has not lifted its suspension of his country's membership.
This has triggered sharp disagreement among African countries, particularly southern African states.
The Commonwealth's key members, Britain, Australia and New Zealand want to see Zimbabwe isolated and punished for its violation of human rights, intimidation of the opposition and harassment of the media.
But countries like South Africa, Namibia, Mozambique and Zambia are angered by the Commonwealth's stand and are saying that Zimbabwe is not being treated equally.
