Usual flag (8)

I believe the answer is:

standard

I believe this is a double definition.

'usual' is the first definition.
(synonyms)

'flag' is the second definition.
(I know that flag can be written as standard)

(Other definitions for standard that I've seen before include "Big tree specially trained" , "authority" , "thing seen looking down The Mall?" , "Stock - basic - flag" , "Classic" .)

I've seen this clue in The Sun and The Daily Express.
