Waits in the wings for champions (6,2)

I believe the answer is:

I believe this is a double definition.

'waits in the wings' is the first definition.

'champions' is the second definition.
(to stand by someone is to support or champion them)

'for' acts as a link.

(Other definitions for stands by that I've seen before include "fails to intervene", "gives support", "Holds oneself in readiness", "Is supportive", "Is ready".)

I've seen this clue in The Times.
