Blimey this has been a hard hard slog, can someone please put me out of my misery and give me the last one? My brain is well and truly fried! I can't say as this has been the most enjoyable crossword!

I'm presuming it's a special one as I'm only counting 4 on my across clues at the min and this is the last one in.
Thanks
