Current leader of KGB, boring communist, gets bugged (5)
I believe the answer is:
irked
'bugged' is the definition.
(I've seen this in another clue)
'current leader of kgb boring communist' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'leader of' indicates taking the first letters.
'boring' indicates putting letters inside (to bore something can mean to drill into it).
'communist' becomes 'red' (red can informally mean communist).
The initial letter of 'kgb' is 'k'.
'k' going inside 'red' is 'rked'.
'i'+'rked'='IRKED'
'gets' acts as a link.
(Other definitions for irked that I've seen before include "Irritated - bothered" , "Galled" , "Vexed, annoyed" , "disgusted" , "Irritated, vexed" .)
