Provides funds though insiders managed party in a haphazard way (2,6)
I believe the answer is:
at random
'in a haphazard way' is the definition.
(I know this)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for at random that I've seen before include "In no prearranged order" , "without purpose" , "without prior arrangement" , "Indiscriminately" , "willy-nilly" .)
