It's to gain access to the DVD changer for vehicles fitted with RSE (Rear Screen Entertainment). You can eject the cartridge and squeeze it through the hole!

I think it also gives access to the manual release for the fuel filler cover so you can still fill up when the damn thing decides it's gonna jam shut as you have a queue of cars building up behind you at the pumps!  2013 Discovery HSE Luxury - 3.0 SDV6 - Santorini Black

Its also a good place to store a towing strap and a torch. If you have a black RRS with tinted windows its also where you can store your stash......  RRS TDv8 HSE Rimini
