Makes sense, I think. Are we basically saying the cable is probably fucked somewhere in the run? I’m not sure what the size is but it’s heavy twin & earth and the main conductors only just fit into socket terminals. Chased into the wall behind tiles (which is where a popping noise comes from when the MCB trips).

Surely this is suggesting fucked cable.
Could disconnect fused switch and see if you have continuity between EL, EN, LN.With the breaker off, of course.

32A on a radial will need 4mm T&E.
You've either got a high resistance fault between L and E or hidden behind the tiles is an old socket and there is choc bloc where the L and E has been miswired or loose connections.
Either way you'll need to get the tiles off to find it.

If the earth is broken somewhere its apparent voltage will free float. If there's also a high resistance fault to live its measured voltage will become that of live. Whereas continuity will only buzz if there's a low resistance between the conductors.
