His interrogation, from 10.00 am to 2.00 pm, relates to allegations that big onions had been bought from local farmers at high prices in order to gain their support at the last presidential election.
Investigations have revealed that several tons of the purchased big onions had been destroyed as there were not enough storage facilities.
Jayasundara had allotted money to buy the big onions at high prices, after the presidential election was announced.
He had ordered that the big onions be purchased at Rs. 90 per kilo, although the cabinet approval was for a price of Rs. 60 per kilo.
As a result, most farmers sold their produce to the state, but the purchased big onions were destroyed due to a lack of storage space.
