Mourners gathering outside Buckingham Palace are being told to stop bringing Paddington Bear toys and marmalade sandwiches as tributes to the Queen.
Queen Elizabeth died on Thursday (local time), prompting an outpouring of grief from the UK and across the world.
Within hours, tens of thousands of people had laid flowers at Green Park outside Buckingham Palace, in scenes reminiscent of the events following Princess Diana's death 25 years ago.
As well as bouquets, mourners have also been bringing Paddington Bear toys and marmalade sandwiches to lay at the gates.
On Thursday (local time), Paddington Bear posted a heartfelt tribute online, saying: "Thank you ma'am, for everything." The bear and the Queen had appeared in a brief two minute sketch ahead of the Queen's Platinum Jubilee in June, which saw an outpouring of love and waves of patriotism.
In the sketch, Paddington and the Queen shared a marmalade sandwich.
However, the tributes have now prompted park bosses to implore the public to only bring unwrapped flowers, which can decay down, as opposed to items wrapped in plastic which would prove difficult to dispose of.
Following consultation with royal gardeners, the public has also been asked not to bring any more marmalade sandwiches.
"Unfortunately, no gifts and artefacts will be accepted and the public will be asked not to bring these to the parks.
"Non-floral objects/artefacts such as teddy bears or balloons should not be brought" the Royal Parks' website said.
The website said wrapping from flowers should be removed before they are left as a tribute to help with their longevity and composting.
It's planned that flowers will be composted after the Queen's funeral on Monday, September 19.
Composted material will be used on shrubberies and landscaping projects across Royal Parks.
