I believe the answer is:

pry

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

'use leverage' is the definition.
'pry' can be an answer for 'leverage' (thesaurus). I'm unsure of the 'use' bit.

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for pry that I've seen before include "Intrusively enquire" , "Be nosey" , "Intrude" , "Snoop or lever" , "Be inquisitive" .)

I've seen this clue in the Evening Standard.
