With a spur (from a ring) or the particular setup described by the OP

load the cable beyond what the 13A fuse on the outlet will carry for a
sustained period.

Surely, if it's a double socket (still permitted I beleive) then that
could potentially be 2 x 13A if the spur is unfused.

Strangely enough, a double socket is only required to be designed to take
a total of (IIRC) 20 A. But yes, theoretically it could be loaded up to 26
A (or more - a BS 1362 13 A fuse will carry more than 13 A for quite some
time).

This is just about fine on a 2.5 mm2 T&E radial provided the cable isn't
buried in insulation etc etc, but definitely not recommended to run that
kind of load for an extended period, even on a double socket on a ring
main or 4 mm2 radial.
