Sparkplug wire (I believe it is called High Tension Cable in UK) works just
fine up to 40-50kV.  Just make sure it is the copper (often tinned copper)
core, not the resistive stuff.  Here in US it's called "solid core" as
opposed to "suppression". You'll find it a bit expensive... runs about
$1/foot here.

Just as good, for all practical purposes, is regular old house wire (#14 or
#16 solid) inside vinyl plastic (Tygon) tubing.  For that matter, bare wire
works, if properly supported away from grounded things.

And, as mentioned in other posts, the larger coax cable (RG-8, etc.) works
quite nicely.
