I'm aware what the Recognised professions are (so please don't repeat). Either I don't know them long enough or not in touch with them any longer or has passed away or not in the Recognised professions list. Besides waiting, is there any other way round this?
Site like this touches on the topic, but never address the direct question that has been raised (just repeats the criteria).
Update: If you call the passport office and ask for advice they say just to get it done by someone that has known me the longest with an attached letter explaining how long he/she has known me. They have stated this is not guaranteed to be accepted. Just a suggestion for us to try something (Which doesn't help).
Another caveat I should mention is that even if they are on the list, they need to have a valid/current passport otherwise it's useless.
