Requirements of necessity (5)

I believe the answer is:

needs

This clue is a double definition.

'requirements' is the first definition.
(I know this)

'of necessity' is the second definition.
(synonyms)

(Other definitions for needs that I've seen before include "Requires, is in want of" , "Necessities" , "Can't do without" , "Requires or lacks" , "Is desperate for" .)

I've seen this clue in The Globe and Mail and The Irish Independent.
