Confirm, back up (11)

Ross

I believe the answer is:

corroborate

This clue is a double definition.

'confirm' is the first definition.
(corroborating is a kind of confirming)

'back up' is the second definition.
(thesaurus)

(Other definitions for corroborate that I've seen before include "Bear out" , "Back up (a statement)" , "Confirm (a statement)" , "Confirm - support" .)

I've seen this clue in The Times.
