Pete Doherty apologises for singing 'Nazi' anthem

Singer Pete Doherty has apologised after being asked to leave a stage in Germany for performing a verse of the national anthem with Nazi connotations.

Doherty, 30, was booed after singing "Deutschland, Deutschland ueber alles" at a concert in Munich on Saturday that was broadcast live on Bavarian radio.

A spokesperson for the singer said he was "unaware of the controversy" about the anthem's rarely used first verse.
