According to the local media, his wife, Sara, was questioned at the same time regarding the case in an effort to prevent the obstruction of justice, Middle East Monitor reported.
Netanyahu is suspected of providing confidential information to Israel’s largest telecoms company in an effort to receive favourable coverage, according to details of the case.
His wife is thought to have also applied pressure on media mogul’s wives to convince them to change their organisations’ reporting.
This is the first time that Netanyahu has been formally questioned in the case.
The Israeli PM is currently entangled in three other political scandals: Case 1000 which involves allegations that the PM and his wife accepted illegal gifts from businessmen; Case 2000 which accuses Netanyahu of attempting to buy favourable newspaper coverage; and Case 3000, also known as the “submarine scandal.”
