Short president tackles case against washing facilities (6)
I believe the answer is:
bidets
'washing facilities' is the definition.
(I've seen this before)
'short president tackles case' is the wordplay.
'short' means to remove the last letter.
'president' becomes 'biden' (Joe Biden).
'case' means to remove the middle letters.
'tackles' with its middle taken out is 'ts'.
'biden' with its final letter taken away is 'bide'.
'bide'+'ts'='BIDETS'
'against' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Another definition for bidets that I've seen is " washing facilities".)
