"Polling stations close at 2200. Some polling stations still had queues at that time. Those people who had not been given their voting form by 2200 couldn't cast a vote."

There was a bit more to it that that though. There seems to not have been enough facilities (ie stations or booths or whatever) as people were seemingly queuing for up to an hour and a half. And at least one polling station ran out of ballot papers mid evening meaning people who had turned up in plenty time to vote couldn't do so because the organisers made a balls up.
