Smoke coming from red jumper lit at the rear (7)
I believe the answer is:
cheroot
'smoke' is the definition.
(type of cigar)
'red jumper lit at the rear' is the wordplay.
'red' becomes 'Che' (as in Che Guevara, a communist or 'red').
'jumper' becomes 'roo' (short for kangaroo, something which jumps).
'at the rear' suggests the final letters.
The last letter of 'lit' is 't'.
'che'+'roo'+'t'='CHEROOT'
'coming from' is the link.
(Other definitions for cheroot that I've seen before include "smoke" , "Square-cut cigar" , "Type of cigar" , "Variety of cigar" , "One smoked" .)
