It’s anyone’s guess who will be the next Chief Rabbi after Lord Sacks retires in two years.

But two rabbis from abroad tipped as possible successors will be visiting next month and teaching on the London School of Jewish Studies High Holy Days programme.

They are Warren Goldstein, Chief Rabbi of South Africa, who will also be a guest speaker at Lord Sacks’s pre-Rosh Hashanah conference for rabbis.

And Rabbi Dr Jonathan Rosenblatt, of the Riverdale Jewish Centre, New York. The great-grandson of the chazzan Yossele Rosenblatt, he has a PhD in British literature from Columbia University.
