I believe the answer is:
nail
'catch' is the definition.
(thesaurus)
'leaders of new administration in lahore' is the wordplay.
'leaders of' suggests taking the first letters.
The first letters of 'new administration in lahore' is 'NAIL'.
(Other definitions for nail that I've seen before include "Spike, tack" , "Finger feature (and tooth?)" , "Arrest (informal) - fix" , "Hammered pin" , "Fix with a metal spike" .)
