It would depend on an informed engineering judgement as to whether the conductors were securely terminated for me.Just a point.
Two rings or not, in general, what are FIRST thoughts on four (or more) cables in a circuit breaker terminal, whilst carrying out an EICR?
How long is a piece of string, maybe?
Just a point.

It says to me that things have probably been done on a tight budget, i.e. the consumer unit has not got enough ways for what they want to supply.
look out for other things that may have been overlooked!
I dont think you have got mixed opinions, nobody has said this is anything other than bad practice. But the question concerns regulations, and as yet nobody has given an actual regulation that this breaches, and throwing hands up in horror does not count as a regulation.Tell me about it did think it would get so many mixed opinions! Always tell myself it doesn't hurt to have a second opinion on things and as I wasnt certain about this that's what I done. Thank you for the positive outlook and advice ?
But there's a spare way in this particular CU.
You couldn't, because by definition it would be one radial.You could put more than one radial on a MCB but its not good practice.
How is it dangerous, apart from the potential issue with the four conductors in the terminals/cage clamp (which although crap is unlikely to be an issue in real terms)?2 Rings on 32mcb is dangerous are you sure it's not 2 radials?
Still, tight budget could also mean tight on time, not got another breaker in the box?
never mind, its Friday the pub is open, just stick it in the other breaker and we are out of here!!
when you see an obvious short cut like that it makes me look for others.
I fully agree that this is incorrect and should not have been done.
But having said that what are the apparent dangers? I don't see any particular danger attributable to this.
The definition of a circuit is based around everything that is connected to a single way in a distribution board, so this would still count as one circuit, although it is nom-standard.
Just a point.

right or wrong what's the common response to finding a Ring on a 20A MCB or wired in 4mm??
You could probably make sure on that if reconnecting after testing. Available breaker? Terminal and c/b condition? Circuit condition? General install condition?It would depend on an informed engineering judgement as to whether the conductors were securely terminated for me.
Ugly but not dangerous. This circuit, not me (but close enough)
In terms of overload you can overstress the 32A MCB on a ring with only 4 items plugged in, so unless this was conjoining two rings that had been chosen to separate high-demand loads it is not really any worse than a bigger single ring.
What is curious is why was this done? The OP says there is one slot free so probably this was a temporary fix for a failed MCB that has become permanent.
Hey, be careful! You don't know who's lurking.Ugly but not dangerous.
