NEBE said in a statement that voters are also not allowed to wear T-shirts, hats or clothes that display symbols of contending political parties.
The board has also announced that voters should switch their mobile phones off while they are in polling stations in a bid to make the polling process smooth. Moreover, local and foreign observers, election executives are also obliged to switch-off their mobile phones in polling stations.
