People asked to not use Paddington Bears and marmalade sandwich's as Queen tribute

It comes following the death of Queen Elizabeth II on Thursday, September 8, since then thousands of well-wishers have travelled to royal sites to mourn the last of the monarch.

As part of the tributes, mourners have been leaving flowers along with Paddington Bear teddies and marmalade sandwiches. 

The tributes are a nod to Her Majesty's sketch with the children's character during her Platinum Jubilee celebrations.

However, now officials at the sites have asked that "In the interests of sustainability, we ask visitors to only lay organic or compostable material."

Adding that a floral tribute garden has been opened in Green Park just a short distance from Buckingham Palace where people can leave flowers in her memory.

Flowers being left outside Buckingham Palace are being moved to the park at the end of every day.

The charity that manages Green Park, The Royal Parks said on their website: "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."

"Cards and labels will, however, be accepted and will be periodically removed by The Royal Parks’ staff and contractors for storage offsite.

"This process will be carried out with discretion and sensitivity."

They also added that "Visitors must not leave artefacts in any other areas of the parks."

The Royal Parks also told visitors that floral tributes will be monitored and those that have "deteriorated" will be taken to the Hyde Park nursery for processing to remove any remaining packaging, cards and labels and to separate plant material for composting in nearby Kensington Gardens.

Tributes will stay in the park during the period of mourning with floral tributes expected to be removed between a fortnight and week after the Queen's state funeral on Monday September 19.
