A European Commissioner calling for a ban on swastikas has been sent a threatening letter posted in Dorset.
Mr Frattini was sent hate mail from Dorset
Police are investigating after Italian Franco Frattini, who is in charge of justice and home affairs policy, found the letter in his post.
Mr Frattini called for an EU-wide ban on Nazi symbols after Prince Harry's party costume caused outrage.
Police investigating the Dorset link say the letter contained a British stamp and a Dorset postmark.
The letter, which carried a large swastika, was written in Italian and stated: "Political pygmies like you won't conquer national socialism."
Mr Frattini said: "I will not be put off. I will continue to work with even greater determination.
"If that creates this kind of threat then I believe the right response is to carry on my job with full commitment."
