Nathaniel is at the centre of a row involving George Osborne, whom he alleged requested illegal donations to the Conservative party. But is this one of the Jewish Rothschilds?
For: The Honourable Nathaniel Philip Victor James Rothschild, known as Nat, is the 35-year-old scion of wealthy Jewish banking family the Rothschilds. His father, Jacob Rothschild, is the fourth Baron Rothschild, who follows the financial family's charitable interests in Israel and is the chairman of Yad Hanadiv, the family foundation which gave the Knesset and the Supreme Court buildings to Israel. Nat is director of the Rothschild Foundation, which aims to support and strengthen Jewish life in Europe. He has been linked with Hollywood's haimishe princess Natalie Portman, and says he would like to meet a nice Jewish girl. Now, could this be the ultimate 100% man?
Against: Oy, if only. It's not that bankers have suddenly become less-than-eligible son-in-law material. It's that Nat's mother, the Canadian Serena Mary Dunn, is not Jewish. Plus, educated at Eton, Nat went on at Oxford to become a member of the distinctly Waspish Bullingdon Club, famous for its drinking binges - and we're not talking Palwin. And far from being obviously neurotic, Mr Rothschild had a distinctly unstereotypical reputation as a playboy. He also married Annabelle Neilson in Las Vegas, without the help of a rabbi.
Verdict: His blood is too blue to be Jewish.
