While there hasn’t been an official invitation or notice, the RCEM has strongly indicated here that the annual award ceremony for new FRCEM/MRCEM diploma recipients will be held on 6 December 2018 in Central London.
So save your leaves and book your tickets for a UK trip! It’s Christmas season and Europe will certainly look beautiful that time of year!
Edit (25/7/2018): They have just confirmed the ceremony date and venue here. Those eligible can expect an invitation anytime soon!
