Mr Netanyahu is under suspicion over the alleged receipt of expensive gifts from wealthy businesspeople and claims of collusion with newspaper publishers in an attempt to secure more favourable coverage.
He is also expected to be questioned on the “submarines” investigation, in which a number of senior military officials and political advisors are suspected of having received bribes in return for the purchase of warships for the Israeli Navy from a German shipyard.
He has denied any wrongdoing, and has accused police of conducting "a transparent witch-hunt" and allowing illegal leaks from the investgation.
On Friday, Israeli media reported that Germany had secretly approved the construction of three submarines to be sold to Israel’s navy.
It is understood that Germany will have the right to withdraw from the deal if police find bribery was involved.
