Encouragement not covered, needing involvement of Government (5)

I believe the answer is:

nudge

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

'encouragement' is the definition.
(I have seen 'Gentle encouragement' mean 'nudge' so perhaps 'encouragement' could also mean 'nudge')

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for nudge that I've seen before include "Push (with a wink?)" , "Jog" , "Jogger" , "Slight push" , "Poke gently with elbow" .)

I've seen this clue in The Independent.
