I'm a little stuck... Click here to teach me more about this clue!

'insurance?' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for cover that I've seen before include "Mask, hide" , "Lid or shelter" , "Overlay" , "Encompass" , "Enshroud" .)

I've seen this clue in the Evening Standard.
