Withdraw tender without any prompting? (5)

I believe the answer is:

unbid

This clue is a double definition.

'withdraw tender' is the first definition.
(unbid could mean to remove a bid)

'without any prompting?' is the second definition.
(unbid or unbidden can mean without being asked)

(Other definitions for unbid that I've seen before include "Like suit nobody likes" , "not ordered" .)

I've seen this clue in The Guardian.
