I hesitate to say it, but that looks like an error. I also couldn't get the wordplay on these - help much appreciated...
24a Guilty-looking churl, first to be executed? (7) - HANGDOG (Guilty looking)
35a Go mad as disrespectful person went smoothly on (4,4,3) - FLIP ONES LID (Go mad)
I presume 'Went smoothly on' is SLID, but can't see the rest.
53a Arrange to keep a newborn from among many in litter (9) - PALANQUIN (Litter)
