Press even has PM's home number (7)

Ross

I believe the answer is:

flatten

I'm a little stuck... Click here to teach me more about this clue!

'press' is the definition.
(thesaurus)

'even has pm's home number' is the wordplay.
'even' becomes 'flat' (similar in meaning).
'has pm's home' becomes 'te' (I can't explain this - if you can you should believe this answer much more).
'number' becomes 'n'.
'flat'+'te'+'n'='FLATTEN'

Can you help me to learn more?

(Other definitions for flatten that I've seen before include "Squash" , "Make smooth or level" , "Floor" , "Raze to the ground" , "'Crush, trample (7)'" .)

I've seen this clue in The Guardian.
