An etiquette expert has told 5 live that, although the guest beds in Windsor Castle now have duvets, it鈥檚 鈥渧ery unlikely鈥� the queen doesn鈥檛 have an eiderdown on her own bed.

William Hanson, who works for an etiquette consultancy, was responding to the news the royal residence is swapping eiderdowns for modern duvets in the guest bedrooms.

Mr Hanson went on to say that eiderdowns "require effort鈥� but big rattling old houses ...aren't double glazed" so they are well worth it.

According to The Daily Telegraph, castle staff aren鈥檛 too pleased about the change because they say the use of eiderdowns is "one of those traditions that should be retained."
