Not so really, a ring circuit is protected by a 32amp breaker but it's
quite alloweable (by IEE regulations) to have a spur wired in 2.5sq mm
cable.

But you're not allowed to run a 32A radial in 2.5mm cable. Yes, I know
it's the same thing at the end of the day but one scenario complies
with BS7671 and one doesn't.

But a radial in 2.5sq mm could have multiple sockets, the spur on a
ring circuit is explicitly only allowed to have one socket (or double
socket) on the end of it.

It's not perfect as, while a double socket is only 'officially' rated
at 20 amps, in reality it could have 26 amps sucked out of it without
the plug-top fuses going.
