I am stuck on the bottom left hand corner
45d: What helps raise protection for baby around vehicle (6)
The only letter I have is -I---- assuming I am correct that 47 across is
'insuperable'
In high state, queen wearing fashionable fur is unbeatable (11)
I'm also stuck on top left, 1 across even tho I have lots of letters
c-l-/p-o-e
The clue is: mobile cadre has to sharpen up after pressure (4/5)
Thank you!
