The Babyshambles star was hauled off stage at the on3 Festival in Munich after singing the opening lines of The Song For Germany – from the verse Adolf Hitler used when the Nazis were in power.

After World War II finished, the Germans adopted verse three as their anthem.

In a statement to Sky News, Doherty's spokeswoman said Pete "wanted to celebrate his appearance in Munich by assimilating and integrating with the crowd, something he tries do wherever he goes.”

She cointinued: "He was unaware of the controversy surrounding the German National anthem and he deeply apologises if he has caused any offence.

"Peter himself is from Jewish descent and has fought against racism and fascism with numerous organisations including Love Music Hate Racism.

"This is a subject he feels very strongly about."
