 Bumper-off job, but easy enough to do as a DIY task.

Probably coolant in the plug well recess(es). Detach a coil from some of the plugs in the area of the leak and see (single special locating bolt, 7mm I think; careful not to drop it). No need to detach the electrical connector on the COP to be able to pull it off the sparkplug and out enough to look. Probably soaking wet. If you have a OBD-II tester, you will probably see P-codes pending, showing precisely which plug(s) are misfiring.
If so, look towards fixing/replacing the leaking manifold ASAP, otherwise the long springs in the coil-tubes which connect to the plug-caps, will start to rust, necessitating replacement of the COP. Anyway a leaking manifold will only get worse, whether it be a gasket or "plastic rot"

Cheers! . Is the gasket easy enough to replace? And where to buy in the UK?

Also where best to get a manifold in the UK if its cracked/no good?

Side question about the manifold, does coolant only flow though the separate pipe on the front of the manifold?

If it does, I'm curious why they bothered sandwiching the plastic manifold between it and the head? And not directly to it.

But I'm probably missing something in the design.
