Fed up with money leaving, putting the squeeze on education (7,3)
I believe the answer is:
brassed off
'fed up' is the definition.
(I've seen this before)
'with money leaving putting the squeeze on education' is the wordplay.
'with money' becomes 'brass' (I can't explain this - if you can you should give a lot more credence to this answer).
'leaving' becomes 'off' (I've seen this in other clues).
'putting the squeeze on' indicates putting letters inside (some letters squeeze around others).
'education' becomes 'ed' (abbreviation - e.g. sex ed).
'brass'+'off'='brassoff'
'brassoff' placed around 'ed' is 'BRASSED OFF'.
(Other definitions for brassed off that I've seen before include "Fed up" , "Exasperated" .)
