The accused government officials were ordered by ministers to destroy any documents available that relates to Nkandla project. The officials spoke on condition of anonymity as they are facing disciplinary hearings.
According to the officials, ministers told them to leave no paper trail or recordings of Nkandla meetings held during the construction period.
Before they participate in meetings, the officials were instructed to leave phones in their cars so no recordings could be made. Personal notes had to be left behind when the meetings were over so no written record could leave the room. Orders were given that no recording be made at some progress meetings and site meetings.
Government departments including public works, defence and police were intimately involved in the upgrades.
The charges against the 13 officials include financial misconduct, allowing irregular spending and failing to follow tender procedures.
