The cold tap on the bath has jammed. The plunger that's supposed to ride
up and down is jammed solid and so far has resisted any attempts at using
brute force to move it.

Any ideas?

Have you removed the mechanism then?

Does it have a circlip on the spindle - if so remove it and knock the
splined shaft down to push out the plunger.

I am guessing that a washer has become so compressed that the plunger has
extended too far and then cannot retract as it has rotated out of alignment
with the hexagonal hole it slides in.
