Fans of the current chief rabbi have mounted a bid to keep him in the post after his official retirement.
Lord Sacks announced two years ago that he would be stepping down in September 2013, after a total of 22 years at the helm of the United Hebrew Congregations.
But with his successor yet to be named, supporters are hoping he will reconsider.
A petition has been launched asking the United Synagogue to consider extending his tenure "for a further negotiated period".
