Withhold information - about an increase in the premium? (5,2)
I believe the answer is:
cover up
'withhold information' is the definition.
(I've seen this before)
'about an increase in the premium?' is the wordplay.
I cannot quite see how this works, but
'about' could be 'over' (both can mean around) and 'over' is located in the answer.
'increase' could be 'up' (upping is a kind of increasing) and 'up' is located in the answer.
A single letter 'c' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cover up that I've seen before include "Attempt at concealment" , "Withhold information" , "cost of insurance has risen" , "Conceal" , "whitewash" .)
