Accuses me of participation in sabotaging labs (6)
I believe the answer is:
blames
'accuses me' is the definition.
'blames' can be an answer for 'accuses' (blaming is a kind of accusing). I'm not sure about the 'me' bit.
'participation in sabotaging labs' is the wordplay.
'participation' becomes 'me' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' means one lot of letters goes inside another.
'sabotaging' is an anagram indicator (I've seen this in other clues).
'labs' with letters rearranged gives 'blas'.
'me' put within 'blas' is 'BLAMES'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for blames that I've seen before include "Holds responsible for fault or misdeed" , "Deems to be responsible for a misdeed" , "Considers someone responsible for" .)
