Show solidarity with no slackers about (5,5)
I believe the answer is:
close ranks
'show solidarity' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'with no slackers about' is the wordplay.
'with' is a charade indicator (letters next to each other).
'about' indicates anagramming the letters.
'no'+'slackers' is 'noslackers'.
'noslackers' with letters rearranged gives 'CLOSE RANKS'.
Can you help me to learn more?
(Other definitions for close ranks that I've seen before include "Unite as a defensive measure" , "Display solidarity" , "make cabbies go out of business?" , "Unite in order to defend common interests" , "to put taxi firms out of business?" .)
