I believe the answer is:

taut

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

'under stress in corrupt autocracy' is the definition.
I can't judge whether this definition defines the answer.

'in corrupt autocracy' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TAUT' is hidden within 'corrupt autocracy'.

Can you help me to learn more?

(Other definitions for taut that I've seen before include "Held in tension" , "Tightly drawn" , "seaworthy" , "Fully stretched" , "On the slope" .)

I've seen this clue in The Sun.
