The rating changes from IMC to IR (r), so IMC no longer exists!
Not true! The IMC rating may be entered into an EASA licence as an IR(R) but that doesn't stop it being an IMC rating. It is still entered as such into a UK national PPL and, given the current moves to permit flight under IFR in UK Annex II aircraft, may long continue to be so.
How does the old saying go? When you find yourself in a hole.......
