Hotshot from Ritz regularly put in charge (6)
I believe the answer is:
wizard
'hotshot' is the definition.
('wizard' can be a synonym of 'hotshot')
'ritz regularly put in charge' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'put in' is an insertion indicator.
'charge' becomes 'ward' (I've seen this before**).
The alternating letters of 'ritz' are 'iz'.
'iz' placed into 'ward' is 'WIZARD'.
'from' is the link.
(Other definitions for wizard that I've seen before include "Ripping" , "Male wand-waver" , "Genius" , "Jolly good" , "speller" .)
