US elder statesman paying respects to The Queen (9)
I believe the answer is:
kissinger
'us elder statesman' is the definition.
(Henry Kissinger)
'paying respects to the queen' is the wordplay.
'paying respects to' becomes 'kissing'.
'the queen' becomes 'er' (Elizabeth Regina).
'kissing'+'er'='KISSINGER'
(Other definitions for kissinger that I've seen before include "Henry --, US diplomat" , "Old statesman" , "Henry __, US Secretary of State under Presidents Nixon and Ford" .)
