Puzzles about what might move the public (7)

I believe the answer is:

rebuses

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

'about what might move the public' is the wordplay.
'about' becomes 're' (regarding).
'what might move the public' becomes 'buses'.
're'+'buses'='REBUSES'

(Another definition for rebuses that I've seen is " Word-picture puzzles".)

I've seen this clue in The Telegraph.
