Israeli police are expected to fly to London to question Soviet-born billionaire Len Blavatnik in relation to the corruption charges facing Benjamin Netanyahu.
Officials want to ask Mr Blavatnik whether Mr Netanyahu was involved in the sale of a TV channel to the billionaire.
Mr Blavatnik, who owns Israel’s Channel 10, will be quizzed by police on whether Mr Netanyahu tried to assist in the purchase between the billionaire and the Yedioth Ahronoth newspaper publisher Arnon Mozes.
According to a Channel 2 report, Mr Netanyahu is suspected of being involved in a deal with Mr Mozes that would have impeded rival newspaper Israel Hayom. In return he is believed to have expected positive coverage from Yedioth Ahronoth.
