Els on the links
I believe the answer is:
ernie
'els on the links' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ernie that I've seen before include "Machine that randomly selects Premium Bond winners" , "It picks Premium Bond winners" , "- - Bevin, 13 dn" , "Eric Morecambe & - - Wise" , "Name given to selector" .)
