Spokesperson to turn and falsify (4,6)
I believe the answer is:
spin doctor
'spokesperson' is the definition.
(spin doctor is a kind of spokesperson)
'turn and falsify' is the wordplay.
'turn' becomes 'spin' (spin is a kind of turn).
'and' is a charade indicator (letters next to each other).
'falsify' becomes 'doctor' (I've seen this before).
'spin'+'doctor'='SPIN-DOCTOR'
'to' acts as a link.
(Other definitions for spin doctor that I've seen before include "Public relations expert" , "spokesperson" , "Massager of news etc" , "Supposed PR expert" , "Government communicator" .)
