Western conspiracy nutter starts to taunt super-rich Gates (7)

I believe the answer is:

wickets

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

'gates' is the definition.
(I know this)

'western conspiracy nutter starts to taunt super-rich' is the wordplay.
'western' becomes 'w'.
'conspiracy nutter' becomes 'Icke' (conspiracy theorist David Icke).
'starts to' says to take the initial letters.
'super-rich' becomes 's' (this could be a standard abbreviation I've not previously seen).
The first letter of 'taunt' is 't'.
'w'+'icke'+'t'+'s'='WICKETS'

Can you help me to learn more?

(Another definition for wickets that I've seen is " Sets of stumps".)

I've seen this clue in The Independent.
