Left-wing record of obstructive bureaucracy (3,4)
I believe the answer is:
red tape
'obstructive bureaucracy' is the definition.
'red tape' can be an answer for 'bureaucracy' (red tape means bureaucratic processes). I'm not certain of the 'obstructive' bit.
'left-wing record' is the wordplay.
'left wing' becomes 'red' (red can informally mean communist).
'record' becomes 'tape' (synonyms).
'red'+'tape'='RED-TAPE'
'of' is the link.
Can you help me to learn more?
(Other definitions for red tape that I've seen before include "Bureaucratic papers and routines" , "Intricate official routine" , "unnecessary paperwork" , "officialdom" , "Bureaucratic ribbon" .)
