I don't know if it was closing properly before. This door is in the guest bathroom so I have never noticed this issue until last week and I started doing some drywall repair before painting. No one ever (guests) mentioned anything about the door latch not working
The door is not installed in a load bearing wall.
I have checked the level of the floor and it's perfect.
Thanks again for your help.

if thats the case its very possible that the door was never hung correctly in the first place.. based on the photos you providied i was looking at the mitres on hte casing to see if the mitres have opened up which is a sign of the structure moving... this being said the latch side of the header wasnt set to a even reveal along the top of the door which in turn will effect the height of the strike plate..
do as joe stated and pull the casing and reset the door
