Fresh lead possibly given by F.D.R. (3,4)

I believe the answer is:

new deal

I'm a little stuck... Click here to teach me more about this clue!

'f d r' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'fresh lead possibly given' is the wordplay.
'fresh' becomes 'new' (similar in meaning).
'possibly' indicates anagramming the letters.
'given' is a charade indicator (letters next to each other).
'lead' with letters rearranged gives 'deal'.
'new'+'deal'='NEW DEAL'

'by' acts as a link.

Can you help me to learn more?

(Other definitions for new deal that I've seen before include "that follows shuffle" , "old line from Washington" , "that follows reshuffle" , "Answer to depression" , "offered by Roosevelt" .)

I've seen this clue in the Evening Standard.
