Manyenyeni said the signposts were temporary and illegal as they were erected without council approval ahead of the Zanu-PF congress that ended last week.
After the event, the former open space seems to have lost its look amid reports that Zanu-PF government was looking into building a permanent structure and maintain the name Robert Mugabe Square and the small roads.
Manyenyeni said that the Zanu-PF event was like a wedding and all balloons should therefore be removed.
