After the show the hives were to be taken to the roof garden of Fortnum & Mason in Piccadilly to make honey to sell in the shop. A spokeswoman for the show, which attracts more than 150,000 visitors every year, said safety was paramount.
She said: "We do not want to aggravate bees trying to get to their pollen and then have a situation on our hands that we couldn't deal with. "Bees have turned out to be quite a theme in a lot of our exhibitions this year but nobody has been given permission actually to have the insects on site."
