Light fitting wires

[Stevie R]

So I’ve attached another photo showing the three wires middle being the earth, there’s been lots of replies posted all are appreciated but it’s become a bit confusing what to do and how, so the picture shows 3 wires one of which is earth the others are a live and neutral but which will be which or does it not matter? The mains wires are clearly identified as L N E

first need to find the core that is connected to the metal body and connect that to the earth/CPC terminal of the rose, then you need to find the core the is attached to the centre/ bottom of the lamp holder, then connect that to the switch live terminal in the rose, and the core that is left must go in the natural terminal of the rose, send a picture of the rose and we can tell where the terminal are

a better photo (maybe in focus)

I'll say this once more it does not matter and those suggesting otherwise refuse to accept this.
