Approximate guide in digital governance? (4,2,5)
I believe the answer is:
rule of thumb
I believe this clue is a double definition.
'approximate guide' is the first definition.
(a rule of thumb is an approximate guide or rule)
'digital governance?' is the second definition.
(the thumb is a digit)
'in' is the link.
(Other definitions for rule of thumb that I've seen before include "Little Tom-ocracy's" , "digital governance?" , "broad principle?" , "Practical guide" , "Rough-and-ready practice" .)
