One supporter left, say (3)

I believe the answer is:

leg

I believe this clue is a double definition.

'one supporter' is the first definition.
(eg support for a table)

'left say' is the second definition.
(left leg)

(Other definitions for leg that I've seen before include "Run < on" , "prop" , "Support; cricket side" , "Section of journey; limb" , "Lower limb" .)

I've seen this clue in the Evening Standard.
