In Stockholm they say they won't hold stuff in the instructions, but if you do have something that you can't enter with, they will. I guess they just don't want to be inundated with stuff.
I don't know about U.S. embassy in London, but in St Petersburg (Russia) they kept your items in a numbered box at the entrance. That was about 3 months ago.
