If the existing ones have been properly fixed, be prepared for some
plastering!
Because of seriously naff wall construction, I'm tiling over existing
tiles.
Group opinion on this is mixed do a Google group search for tiles on tiles

Well, my opinion... I've taken tiles off before and the wall required
replastering. I have recently just done my bathroom here, and tiled over
existing ones. I didn't have too many problems...
