Guys, I think we're mixing 2 different topics here.
The thread was started WRT an IR renewal, NOT your licence renewal.
As discussed, all you need to have a valid licence is a medical and any aircraft type rating on it, but what the thread starter is talking about is your IR. You can have a current licence without an IR rating.
Again, does anyone have a copy of LASORS 2008, because as Peeproone said, if the UK CAA arbitrarily removed the ICAO rule then I think there is a case to be had.
