Decline accompanying the Queen (6)

I believe the answer is:

wither

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

'accompanying the queen' is the wordplay.
'accompanying' becomes 'with' (I've seen this before).
'the queen' becomes 'er' (Elizabeth Regina).
'with'+'er'='WITHER'

(Other definitions for wither that I've seen before include "Dry up, decay" , "Writhe (anag.)" , "Shrink, shrivel up" , "Writhe about and shrivel" , "Shrivel and decay" .)

I've seen this clue in The Telegraph.
