Swift Celeste internal lights

I have a Swift Celeste 15/2 and need to change the bulb or maybe the socket in the wall light ( see photo) but cannot see how to remove the shade or cover.

I can see that it is fixed to the wall with screws from the front but don't want to force it as it is plastic and therefore probably brittle with heat and age.
