No. 9457, Monday, 16 Feb 09, Sankalak

Monday morning blues. Got stuck on 14A and 15D. Otherwise I found it to be a very invigorating with a lot of new words added to my vocabulary. Posting without the above two answers to meet my deadline. (Addendum - Got stuck on 15D as I took "Is Emil fit" instead of "Emil fit to" as the anagram fodder, kicked myself for getting stuck on 14A which turned out to be so easy.)
