Control said to be restored (10)
I believe the answer is:
reinstated
'be restored' is the definition.
(I've seen this before)
'control said' is the wordplay.
'control' becomes 'rein' (rein is a kind of control).
'said' becomes 'stated' ('state' can be a synonym of 'say').
'rein'+'stated'='REINSTATED'
'to' acts as a link.
(Other definitions for reinstated that I've seen before include "restored" , "brought back" , "being put back" , "Got back to work" .)
