We have been reliably informed (but it is still a rumor) that the rules for the election will ban exit polling.
Exit polling is a simple method of determining if the votes counted represent the votes cast. People leaving the polling station are asked if they wish to indicate who they voted for. They are free to refuse but normally 42% will freely answer and in the US it is accurate within 15%. It is used in most democracies including USA. While not super accurate it gives an early indication of how people voted.
The only reason I can think of as to why the Electoral Commision would want to stop this is that there may be a major discrepancy between who people say they have voted for and the final counted vote. This may result in claims of vote rigging.
Could one of the registered parties please query this with the Commision.
