Revolutionary place to hide bread overseas (4)
I believe the answer is:
rial
'bread overseas' is the definition.
(currency of Iran - 'bread' can mean money)
'revolutionary place to hide' is the wordplay.
'revolutionary' shows that the letters should be reversed in order.
'place to hide' becomes 'lair' (I've seen this before).
'lair' in reverse letter order is 'RIAL'.
(Other definitions for rial that I've seen before include "Middle Eastern money" , "Ready" , "Bit of money" , "foreign money" , "Cash" .)
