The Queen - in cake form

One of the more unusual tributes being planned for the Diamond Jubilee is a new portrait of the Queen - but one being made out of cakes.
The idea of German-born chef Gerhard Jenne from Konditor & Cook, the image will be made up of 3,120 individual cakes - one for every week of her reign - iced to create a pixellated composite portrait.
The final cake portrait, which will be displayed in London's Battersea Park, will take three to four days to create - and once unveiled, the public will be invited to buy a piece of it, in exchange for a charity donation.
BBC News went along to see a trial run of 500 cakes being put together.
