Something wrong in government desire to squash left (6)
I believe the answer is:
glitch
'something wrong' is the definition.
(a computer problem)
'government desire to squash left' is the wordplay.
I cannot really understand how this works, but
'government' could be 'g' (abbreviation for government) and 'g' is located in the answer.
'desire' could be 'itch' (itch is a kind of desire) and 'itch' is present in the answer.
'left' could be 'l' (common abbreviation) and 'l' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for glitch that I've seen before include "Fault (electronics)" , "Malfunction or snag" , "Temporary fault" , "Irregular computer failure" , "Minor mishap" .)
