Angling shop's opening in a leafy part of London (5)

I believe the answer is:

askew

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

'angling shop's opening' is the definition.
I can't judge whether this defines the answer.

'leafy part of london' is the wordplay.
'leafy' becomes 'as' (I can't explain this - if you can you should give a lot more credence to this answer).
'part of london' becomes 'kew' (I've seen this before).
'as'+'kew'='ASKEW'

'in a' acts as a link.

Can you help me to learn more?

(Other definitions for askew that I've seen before include "Out of line" , "in an odd position" , "Crookedly" , "Leaning to one side" , "Off-centre" .)
