King Charles, with little notion, screwing up (9)

I believe the answer is:

crinkling

'screwing up' is the definition.
(to crinkle is to screw up)

'king charles with little notion' is the wordplay.
'king charles' becomes 'cr' (I've seen this in other clues).
'with' means one lot of letters go next to another.
'little notion' becomes 'inkling' (an inkling is an idea or feeling).
'cr'+'inkling'='CRINKLING'

I've seen this clue in The Times.
