(English libel law doesn't work the same way as US libel law; IIRC, if you can show that a reasonable viewer could have interpreted the broadcast in a way that's both defamatory and false, then that's libel even if the broadcaster never intended it to be understood that way and even if all or nearly all viewers interpreted it correctly.)
