Sobbing Tory leader in weak state (11)
I believe the answer is:
lamentation
'sobbing' is the definition.
(thesaurus)
'tory leader in weak state' is the wordplay.
'tory leader' becomes 't' (I've seen this in other clues).
'in' means one lot of letters goes inside another.
'weak' becomes 'lame' ('lame' can be similar in meaning to 'weak').
'state' becomes 'nation' ('nation' can be a synonym of 'state'**).
'lame'+'nation'='lamenation'
't' put within 'lamenation' is 'LAMENTATION'.
(Other definitions for lamentation that I've seen before include "Keen" , "Show of grief" , "Expression of sorrow" , "A number of swans" , "Moaning" .)
