Terribly cruel MP brought in died, collapsed (8)
I believe the answer is:
crumpled
'collapsed' is the definition.
('crumple' can be a synonym of 'collapse')
'terribly cruel mp brought in died' is the wordplay.
'terribly' indicates anagramming the letters.
'brought in' means one lot of letters goes inside another.
'died' becomes 'd' (abbreviation next to the year of someone's death).
'cruel' anagrammed gives 'crule'.
'crule' enclosing 'mp' is 'crumple'.
'crumple'+'d'='CRUMPLED'
(Other definitions for crumpled that I've seen before include "Creased, wrinkled" , "Wrinkly" , "collapsed" .)
