In 2015 GECOM did not allowed PPPC a recount, so Ballot boxes means nothing, votes are counted at polling booth. the Presiding Officer at each polling station would initiate the process of the counting of the ballots. These ballots are counted in the presence of the polling agents who represent the respective political parties.
Bringing the crowd at the polling booth after poll is closed is intimidation to the opposition polling agents.
I was a polling agent in 1985 at Victoria Village and can relate to this experience.
