Hundreds of kilograms of food taken from people entering Westminster Hall to see The Queen's Lying will be given to London's hungry.
As people line the streets of the capital to see Her Majesty's coffin, most with food and drink, any left over is being picked up from Victoria Tower Gardens and redistributed to those in need.
Charity The Felix Project says many of the thousands of well-wishers have arrived with picnic boxes to keep themselves full on the mammoth queue.
And instead of throwing it out and wasting it, they will be collecting all non-perishable goods and unopened packages and handing them out to charity and community groups in London.
Felix Project chief executive Charlotte Hill was at Westminster to help move the first load of food collected.
She said: “We are honoured to be here to play a small part in this hugely poignant event and to know that an extra layer of good is being done here today.
"This food is a hugely unique donation and will help hundreds of people who are struggling to afford to eat.
"We support thousands of organisations helping a huge range of people and every day more are getting in contact asking us to give them food. We need more food, so opportunities like this are truly wonderful.”
The opportunity came about after the Scout Association reported seeing loads of food being chucked in the bin and wasted.
Now, as more people join the queue it isn't just food being collected but blankets as well.
Officials spent the night giving people blankets to stay warm, which are then being discarded as people get to the front.
The Felix Project will give half the blankets to charities that support the homeless in London.
The other half will be given to organisations that are sending supplies to Ukraine. The blankets will make up care packages to help those still living in the war-torn country.
Over the weekend the charity will be visiting the site a number of times. All the food will then be taken to the Deptford depot to be sorted and sent out to those in need.
