As usual, quite a variety of quality clues, putting a lot of pressure on me to choose the winner. I endeavored to sift through them all, and hopefully did not sprain my brain in the process.
On a first read-through I gave check-marks to a lot of clues including the anagrams of jono 8, paul 14 and 20 and simon 22; jono's alternating letters at 10; mattrom's hidden at 6; as well as jono 17; aristo 19; and jimmyg's medically dubious double def at 26. However for the ripped-from-the-headlines topicality I have to go with mattrom's hidden at 7:
Truss trainwreck involves tax
Trainwreck seems fine to me; a little googling reveals its not-uncommon usage in the UK press. "Dumpster fire" also seems to apply but wouldn't work for the clue, of course.
Congrats to mattrom and thanks to all for contributing.
