Got rid of the dud MEP, perhaps (6)
I believe the answer is:
dumped
'got rid of' is the definition.
(dumping is a kind of getting rid of)
'dud mep perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'dud'+'mep'='dudmep'
'dudmep' with letters rearranged gives 'DUMPED'.
'the' acts as a link.
(Other definitions for dumped that I've seen before include "Dropped unceremoniously" , "Ditched" , "Deposited as rubbish, or got rid of" , "Deselected" , "abandoned" .)
