Another good puzzle from Julius, as always.  Not as much wit and political satire as we sometimes get but still very enjoyable regardless.  Thank you Julius.

I write these posts to help people get started with cryptic crosswords. If there is something here you do not understand ask a question; there are probably others wondering the same thing.
I did like Bolingbroke!Good stuff as usual-also liked PM and US attorney.
I agree – Bolingbroke is brilliant! And I liked PM and US attorney too, and I enjoyed the construction of AU NATUREL and the neat KYOTO. And lots more.
Many thanks to setter and blogger.
What Eileen said
Thanks to Julius and PeeDee. Enjoyable. I had trouble with the bottom half, largely because I started off with Tokyo rather than KYOTO, so that I took a while getting STREWN, my LOI. I also had trouble at first parsing gAMBIT and the LAN in BLANC.
Thanks Julius, PeeDee
For 10a (no doubt what you meant to say is that) AU NATUREL is ‘Blanc’s simply’, with ‘cooked’ being the anagram indicator.
Also liked AFTERNOON SESSIONS and HENRY IV. I’ve had a good stare, but can’t see if there’s anything going on.
It could also be “22 down’s simply-cooked” with served as the anagram indicator for TUNA.
Fun puzzle thanks Julius. Trying to remember how many b’s in obbligato. And thanks for the 5d namecheck. I like many of the simple ones, strewn, shrub, etc. PM great in 6d.
Many thanks Peedee as usual
@Dutch, that’s better, I was trying to be too clever
Thanks to Dutch and James for the improved parsing for AU NATUREL. James is very kind to imply that is what I meant to write, but not wholly accurate I fear.
A really enjoyable challenge, especially the brilliant Henry IV. Thank you, Julius.
Yes, many pearls….a delight! Thanks Julius and Peedee.
I loved Bolingbroke! Great puzzle. And parsing
Thanks Julius and PeeDee
Late to this after watching a great game in our AFL football grand final yesterday. Whilst this was not quite as enjoyable, it was still pretty good. Like others, I really appreciated 13a after having to look him up to link him to Bolingbroke. A few of them that I had to do that for – Belgravia’s postcode and Jeff SESSIONS.
Missed the parsing of BREAKFAST and finished with REPTILIAN after a very pleasant half hour over a coffee.
