THE voting rights of South African citizens abroad during elections, and of prisoners, will be considered by Cabinet in its Thursday afternoon meeting, according to Ronnie Mamoepa, spokesman for Deputy President Thabo Mbeki. Opposition parties have united to demand that citizens abroad be allowed to vote, following a Constitutional Court decision last week that prisoners should be permitted to vote. Prisoners were allowed to vote during the 1994 elections, but Cabinet had decided that resources do not permit allowing prisoners to vote in the 1999 elections.
