Escape is the way to get into office (3,3,2)
I believe the answer is:
run for it
'escape' is the definition.
(I've seen this before)
'the way to get into office' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'way' could be 'r' (abbreviation for right) and 'r' is present in the answer.
'to' could be 'for' and 'for' is found in the answer.
The remaining letters 'uni' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for run for it that I've seen before include "scat!" , "Seek safety in fleeing" , "Scarper!" , "Try to escape" , "Attempt to escape" .)
