In a special interview published in full in Yedioth Ahronoth's weekend edition, Ben Artzi describes a torn and divided family.
'Sara Netanyahu can make or break anyone'
"During father's shiva we each sat at our own corner at the prime minister's residence," he revealed.
"Sara was my beloved younger sister who I used to give piggyback rides to. We had a very deep and strong relationship. That's why this estrangement is very painful."
Nevertheless, he did not spare criticism from his younger sister. "There is something about my sister today that is lavish and even careless with money," he says. "I keep saying: I know Sara my sister, but I don't know Sara, the prime minister's wife."
"We haven't spoken for nearly 16 years and it's obvious she's changed because we used to have a very deep and profound relationship. I imagine that my parents would have been happier to see more simplicity and humbleness.
"I believe this is part of the leadership the people yearn for, leadership that shows that the leader sees himself as a servant of the people, not someone who takes advantage of the people's resources."
Speaking on behalf of Sara Netanyahu, Attorney Yossi Cohen, said: "It regretful that during a campaign to launch his new book, Hagai Ben Artzi is dragged into the usual tedious smear campaign against his sister Sara Netanyahu, the prime minister's wife."
