A trade union attached to the Ceylon Petroleum Cooperation has made revelations that the institution which certified substandard petrol supplies to the

country on a previous occasion has carried out certifications on contaminated diesel supplies which were imported to the country recently.

A large number of vehicles, including trains and busses stalled as a result of the contaminated diesel supplies which were imported from Singapore recently.

Chief Secretary of the CPC's Jathika Sevaka Sangamaya Ananda Palitha expressed these views concerning the recently contaminated diesel supplies which were certified by the institution in dispute.
