King and queen with leader's headgear (9)

Ross

I believe the answer is:

kerchiefs

'headgear' is the definition.
(items worn on the head)

'king and queen with leader's' is the wordplay.
'king and queen' becomes 'ker' (K for King and ER for Elizabeth Regina).
'with' means one lot of letters go next to another.
'leader's' becomes 'chief's' (chief is a kind of leader).
'ker'+'chiefs'='KERCHIEFS'

(Another definition for kerchiefs that I've seen is " Gumbys' headgear?".)

I've seen this clue in The Times.
