I've never been a fan of the 'primarily' clues unless the primarily indicator is well concealed. Perhaps not labelled 'primarily'!
That said, when one is stuck, it's a help.
Today I stared at a blank grid for ages.
Liked the spoonerism. Rhyming pair ok. Connection between last two down clues (in more ways than one?).
I note the Liz Truss comparison. Amused me.
Thanks Everyman. Online on my phone awful as usual.
