This puzzle has no fewer than three clues that I lack a complete understanding of: 26A, 5D and 21D. My copy of the paper did not include the clue for 23D and I retrieved it from the FT web site.
Across
1. EGGHEAD – double definition. Eggcellent!
5. POMPOUS – POM (Englishman abroad) + anagram of OPUS

10. SEVENTEEN – EVENT (occasion) in SEEN (observed)
11. SCAPEGOAT – S (seconds) + A PEG (a pin) in COAT (jacket)
12. FUNGI – homophone. I have a friend who has used this pun about himself before!
13. WHOOPEE CUSHION – cryptic definition. Not terribly cryptic though.
19. CURRENT ACCOUNT – double definition
20. DEMON – MO (doctor) in DEN (study)
22. TWITTERED – T (model) + WITTERED (waffled on)
24. MENAGERIE – anagram of EMERGE IN A

19. ADJOIN – A (a) + DJ (record player) + O (nothing) + IN (popular)
21. MANGO – ???
22. TURIN – [Alan] TURIN[g]
23. TULSA – A (a) + SLUT (prostitute) reversed
21D MAN (piece) + GO (be eaten)
26A ROUT (hiding) in CONsomme (no ‘somme’ needed)
5D PI + VOT as you have them, PIVOT = spin
23D clue also missing in the US edition, but not hard to guess TULSA!
John, thanks. I still do not quite see 21D. How does “be eaten” clue GO and why the question mark?
Well, if something has been eaten it’s gone. Seemed OK to me. But don’t we always feel peeved at the ones that defeat us? I’m now hoping somebody will explain 21D in 12741. Looks like PREEN (= tidy), by why “… up? No, down!”?
In last line, for “by” read “but”!
