Wrongly call this person strict, not quite keeping two metres apart (7)
I believe the answer is:
misterm
'wrongly call' is the definition.
(to misterm is to name something incorrectly)
'this person strict not quite keeping two metres apart' is the wordplay.
I cannot really see how this works, but
'person' could be 'mister' (mister is a kind of person) and 'mister' is located in the answer.
'metres' could be 'm' and 'm' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
(Other definitions for misterm that I've seen before include "Give wrong name" , "name in an inappropriate way" .)
