Scandalously, Fleet Street scarcely covers spreader of disease (6,3)
I believe the answer is:
tsetse fly
'disease' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tsetse fly that I've seen before include "African insect disease carrier" , "African, blood-sucking disease spreader" , "It spreads sleeping sickness" , "parasite" , "Cause of sleeping sickness" .)
