Famous Russian without a job (5). *r*t*k*. Trotsky, this must be, as per previous post, but can anybody explain the wordplay? I'm bemused.

i can see task without a for the tsk but that's it

Is there a word missing from the clue?I am thinking t(a)sk in Troy.

That's what the clue says...the "task without a" sounds good, but I still can't work out the rest.
