If the cable size is wrong (it isn’t, see later reply) it should be corrected, not an irreverent fuse fitted.
I never said the cable size was wrong. I have not seen the amendments, but there has been mention that 1 Milli cable can now be used on "power" circuits. Even if this is not correct, you can use 1.5.

You haven’t seen the amendments. Winston hasn’t even seen the regulations, so there’s very little chance of getting the story straight

It IS correct. Table 52.3 now has only one relevant row, and that is "Lighting and power circuits", for which the minimum CSA (for copper conductors) is 1.0 mm².

So we’re they wrong fit all those years or are they wrong now?

I don't think that there is any 'right' or 'wrong' about it. All I can say is that few, if any, of us could understand the thinking behind the distinction between 'lighting' and 'power' circuits (with different minimum cable CSAs) which used to exist.

It has always been the case (well, for as long as I can remember) that if one uses a flexible cable, then it can have a CSA as small as 0.75mm², regardless of what one chooses to call the circuit - and that difference from non-flexible cables seems to make even less sense.

Liar. Of course I’ve seen the regs.
Presumably seen from a distance, such as on a library shelf. However from your regular incorrect prattling on here it appears you have never looked inside the book.

my understanding way back in the 1960's was

Lighting circuits had only hard wired lights, no sockets to plug equipment into

Power circuits had only sockets for items that had to be plugged into. Nothing hard wired.

Plugging an electric iron into a bayonet lamp holder hanging from a ceiling rose was at odds with the rules

I also have vague recollections that in some houses power and lighting might have had separate meters with the cost of a kWh being more than the cost of a lighting kWh

All true, but "So what?". If the a 1.0mm² cable has a CCC which renders it adequately protected by the circuit's OPD, then why should it not be allowed if it happens to be a 'sockets circuit'?

I never experienced that, but have often heard it said - but, again, what has that got to do with the minimum CSA of cable in a 'power circuit'?

I recall a terrace of houses with 2 feeds:
A small fused (Possibly 5A as the tenants seemed to be using very low power bulbs) unmetered feed for the whole terraces lights.
A 30A (total for whole terrace) feed with individual meters and a single fuse in the houses for power. The cast iron fusebox on the end of the terrace was left unscrewed as they regularly needed to replace the fusewire.
