The KwaZulu-Natal Transport Alliance has given political parties "two weeks" to contact it.
General secretary Bafana Mhlongo said yesterday that the alliance, which has more than 16000 members, would hold a mass meeting on April 16 to "take an inclusive decision" on which party it would vote for in the April 22 general elections.
The announcement came after insiders said IFP national chairperson Zanele Magwaza-Msibi had met members of the alliance.

"Up to the day of the meeting there were no meetings with political organisations taking place," Ferror said.
