Is there two M's prior to "police" in that column, or is the first a stray M from the preceding column for married/male?
If both M's are in the column, I'm thinking it's M M police corps, as in Mounted Military Police Corps. Notice the small L in "Dealer" and "Appledore". They are quite different, but one matches the top "police", and the other matches the lower "police".
I can't make out what is following the top one (perhaps some abbrev. for Middlesex?), but the lower one looks like "Hants".
