A circular issued on September 26 says uniform material could be purchased from Salusala for children in remote and difficult areas.
A second circular issued on September 03 only mentions about distributing uniform vouchers.
The education secretary has issued these circulars without cancelling the previous circulars.
Meanwhile, a principal has been suspended and several others under investigation for having distributed uniform vouchers.
Noting the ministry secretary has blamed others for his mistake, Fernando urged authorities to take immediate remedial action.
