Needled your MP, unfortunately not getting enough work (13)
I believe the answer is:
underemployed
'not getting enough work' is the definition.
(lacking employment)
'needled your mp unfortunately' is the wordplay.
'unfortunately' indicates an anagram (a bad or unfortunate spelling).
'needled'+'your'+'mp'='needledyourmp'
'needledyourmp' is an anagram of 'UNDEREMPLOYED'.
(Other definitions for underemployed that I've seen before include "Having too little work" , "Not having enough work" , "Not fully made use of" , "Not fully occupied with work" , "Not used enough" .)
