Frydenberg condemns Nazi poster graffiti

Treasurer Josh Frydenberg says vandals who defaced his campaign signs with Nazi symbolism are cowards.

Some of the Victorian frontbencher's election posters have been graffitied with Hitler moustaches, devil horns and the words "right wing fascist".

"Vandalism is unacceptable and these people are cowards," Mr Frydenberg told reporters in Melbourne on Friday.

"It is one thing to graffiti a sign but it is another to invoke the horrors and the evils of the Holocaust and Nazism.

"These people are despicable, they are cowards and they are very ignorant of the horrors of history."
