What's this shrub - please?

How big/tall is it and what's its spread? From the photo it could be a small plant yet you say its a shrub.
Have you had it long or just bought it?

Euonymous?

It's not a weigela or choisya.

Just realised I forgot the picture of the leaves!

Weigelas like full sun but are ok in semi-shade
It's not a good time to move it, March is probably the very latest time and it has become rather warm this week.

Is it a weigela?

I thought a choisya - does it have white flowers in late spring?

However, I am not sure about the purple/green leaves
They don't like full shade.

Skimmia?

Oh, maybe ceratostigma? Does it have blue flowers?

Is is a sickly azalea?

Is it mountain horopito? Otherwise called the pepper tree. I gave google lens a try and the picture it came up with looks exactly like your shrub.

Reminds me of Pernettya. Red or purplish berries in winter?

Dont think so gardener.

The leaves are tinged with red!

Sorry It just reminded (until I belatedly looked at it close-up) of a choisya that I used to have, which was always very sickly until I eventually found a spot in the garden that it liked.

Wondering if it could be sort of periwinkle.

No, it's meant to look like that!

Could it be a very unhealthy-looking choisya?

Closer on the leaves and, of course, I will remember as soon as you tell me!
