There is no need for any document or invitation letter for Tourist Visa. He should just ask for it at Egypt Embassy in the UK, and require it to be lasting for 60 days. This is the longest possible visa which can be required from abroad, but he will be able to extend it at the Ministry of Foreign Affairs office in Luxor if needed. (here is a link where you can find more information about it http://www.worldtravelguide.net/egypt/passport-visa ).
