Multiple lives in junction box

You can use the earth conductor in a flex providing it is marked with the appropriate colour identification for the phase used and is visible at both ends.

This does not apply to cables with a bare ecc, such as twin and earth.

I'm not going to suggest it is good practice or that I would do it myself, but when I did the full scope 17th Edition a few years back this precise question was asked. If there has been any changes wrt earth conductors in flexes since, I'm not aware.

I never knew that?! I thought it was a no no regardless. Good to know if your stuck in a tight spot.

Yeh it's fine to use the earth as a live on double insulated cable. But it must be sleaved with this stuff at both ends

You can't just wrap a bit of masking tape around it and write live on it!
