Hi Doriana. Wonderful to see you again.
True story? yes If not, FYOI? FSEI?
The politician = H/A/M? yes to all
Was the politician active at a national? regional? local level? this Relevant? yesish - largely for context
Did the staff members have a choice whether to get a tattoo or not? hard to say - I would speculate that there would be consequences if they refused, but this isn't what drove them to accept the offer Did they have a choice regarding what tattoo they got? no Where (as in where on their bodies) they got it? no Did they all get the same tattoo? The same style of tattoo, yes
Relevant where on the body the tattoo was? yes If so, arms? legs? head/face this? back? upper body? private parts? no to rest
Not sure if I would call him a politician, but is Lord Voldemort relevant? no (Definition #2 in the Oxford Dictionary is 'a person who is good at using different situations in an organization to try to get power or advantage for himself or herself', which certainly describes you-know-who).
