"I was first given the chance to present my stance on the matter and then the commission asked questions," he added.
Umar said that the commission's report would be finalised soon and would be made public.
"I do not think that Prime Minister Imran Khan needs to appear before the commission," he said, while responding to a question. Umar said that everything would be made clear in the next few days and everyone would know the difference between Imran Khan and others.
He said the commission's report had yet to come so it could not be said that to which country sugar was smuggled and in what quantity.
However, Umar said he role of the Sugar Advisory Board could not be ignored.
Umar had himself requested the commission to summon him instead of the prime minister after the Pakistan Muslim League (PML-N) senior vice president and former prime minister Shahid Khaqan Abbasi demanded the commission to question the prime minister and the finance minister about why the federal cabinet and the ECC had approved the export of sugar when there were not surplus stocks in the country.
