Leakes of reality TV (4)
I believe the answer is:
nene
'leakes of reality tv' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nene that I've seen before include "Peterborough's river" , "River navigable to Northampton" , "Northampton's river" , "Foreign goose" , "Northants river" .)
