One small point re 6dn. “Lions” can also refer to the composite England, Scotland, Ireland (both parts), & Wales Rugby Union touring team, and without wishing to get embroiled in any league v union debate, I would think that the term is better known in this context.

For me, Crux is a setter who, ever since I ‘discovered’ him, nested himself quite firmly in my Top 20 – and this crossword is another example of the reason why.

He has a Rufus-like command of incorporating the English language into clues that read so smoothly and which are completely natural [said the one who isn’t British ].
Some fine examples this time:
“Heads lose carbon copies” for APES (3d).
“Transport sector going in convoy” for ESCORT (22d).
“Fabric woven from finest end of cloth” for FISHNET (15ac).
“It’s a sin to conceal love, say” for VOICE (7d).
“Lie around, definitely relaxed” for LEISURELY (17d).

Crux shows us how a not too difficult crossword can be extremely enjoyable to solve.
And there was sparkle, too.
Like in 29ac, THINKING as opposite to the ‘fat king’ Henry VIII.
Or in the excellent Spoonerism of LETTERBOX (10ac).

I think it’s time for promotion: Crux for the Saturday spot!
[well, if that is promotion]
