To coincide with the start of the Commonwealth Heads of Government Meeting in Brisbane, Australia on Saturday 6 October, there will be two large, colourful, and peaceful demonstrations - one in London, and one in Pretoria. It is very important that a strong protest is registered, to make sure that the delegates to CHOGM fully appreciate the importance of holding the government of Zimbabwe to the public promises it recently made in Abuja and Harare. Pretoria : Starts at noon at the Union Buildings. London : Starts at noon on Saturday 6 October outside the Zimbabwe High Commission.
