29D -- Perhaps I missed it, & I don't want to scan through again, but is this the fellow?
http://en.wikipedia.org/wiki/Denis_Healey
in which case, his name is misspelled.
Don't know the fellow, so ... "sullen" ?
Overall, some brilliant clues, at least ones that boggled me for a while:
17A, 38A, 45A, 40D, to mention a few, & then still unsolved 21D, plus a couple from Les.
MaƱana.
