Mourners are being urged not to leave marmalade sandwiches or Paddington Bear toys at the Queen's memorial at Buckingham Palace.
Her Majesty, 96, had appeared in a sketch alongside Paddington Bear as part of her Platinum Jubilee celebrations in June. In it, she comically revealed she keeps a marmalade sandwich in her handbag - a favourite food of the fictional children's book character.
However, photos on social media have shown sandwiches - left by mourners among the floral tributes in memory of Her Majesty - already going black with mould.
