Nine opposition parties, including the EFF, UDM and DA will march to the Union Buildings in Pretoria on Wednesday to demand President Jacob Zuma's resignation.
The march falls on the president's 75th birthday.
The Tshwane Metro Police Department's (TMPD) Isaac Mahamba said the marchers are expected to gather at Church Square from 10.00am.
"The march will start around 12.00pm to the Union Buildings," said Mahamba.
