Freedom to move with little backing in place (6)
I believe the answer is:
leeway
'freedom to move' is the definition.
(I've seen this before)
'little backing in place' is the wordplay.
'little' becomes 'wee' ('wee' can be similar in meaning to 'little'**).
'backing' is a reversal indicator.
'in' indicates putting letters inside.
'place' becomes 'lay' (laying is a kind of placing).
'wee' reversed gives 'eew'.
'eew' going within 'lay' is 'LEEWAY'.
'with' acts as a link.
(Other definitions for leeway that I've seen before include "Margin of safety" , "Space for free movement" , "Elbow room?" , "Room to manoeuvre, latitude" , "Room to manoeuvre, as for a ship" .)
