Ballot boxes for early voters and postal voting could have been compromised while they were kept by the police, along with indelible ink and other ballot papers for use on polling day, PKR vice-president Fuziah Salleh said today.

She said Election Commission chief Abdul Aziz Yusof had promised that representatives of the candidates could keep watch on the ballot boxes for early voting and they could even sleep in the police cells in which these were kept.
