Slip is the answer to 31 Across (pils backwards), and even given the Telegraph's almost pathological penchant for recycling the same solution to different puzzles in the same issue, I can't thin you're going to get the same answer twice to adjacent clues.
Unless they're getting very cunning....
So, I went for snip, even though the clue makes no sense.
I had this discussion last night with catron and think that Catron has the right of it with SPIN for 31a NIPS backwards.
The argument was that Pils is singular while Nips is plural and the clue quotes drinkS.
I have put SNIP for 26d, but agree that it is not a very good clue.
