Chief Rabbi Ephraim Mirvis was unable to deliver his eulogy at the funeral of Rabbi Lord Sacks because he has been instructed to self-isolate.
Instead, Rabbi Mordechai Ginsbury, of Hendon United Synagogue, delivered the hesped prepared by Rabbi Mirvis for Sunday's levaya.
The Chief Rabbi began his eulogy by writing: "I am truly sorry that having been instructed by my NHS app to self-isolate, I am not able to be here in person."
A message on The Office of Rabbi Sacks YouTube page also said: "This video is of a hesped (eulogy) by Chief Rabbi Ephraim Mirvis who was unable to attend in person due to UK Government COVID restrictions."
