It has long been customary to present your hosts with a gift.
So when Chief Rabbi Ephraim Mirvis and his wife Valerie stayed over at Windsor Castle last night as guests of the Queen ahead of her 90th birthday, they arrived at the royal residence with a special gift in tow.
Rabbi Mirvis presented Her Majesty with a bespoke prayer for the Royal family on behalf of the United Hebrew Congregations of the Commonwealth.
The prayer, which is read out in synagogues every Shabbat morning, was written on watercolour paper and mounted on a gold frame, ready for hanging.
