Head of Equity therefore has journalists in for coffee (8)
I believe the answer is:
espresso
'for coffee' is the definition.
(espresso is a kind of coffee)
'head of equity therefore has journalists' is the wordplay.
'head of' suggests taking the first letters.
'therefore' becomes 'so' ('so' can mean 'consequently' or 'therefore').
'has' indicates putting letters inside.
'journalists' becomes 'press' (the press can mean the newspaper industry).
The first letter of 'equity' is 'e'.
'so' placed around 'press' is 'spresso'.
'e'+'spresso'='ESPRESSO'
'in' acts as a link.
(Other definitions for espresso that I've seen before include "Coffee made under steam pressure" , "that's stimulating" , "It's made by forcing steam through ground coffee beans" , "Seep Ross into the coffee" , "Italian-style coffee" .)
