Rapper K’Naan says he is seeking legal action, upset that Republican Presidential candidate Mitt Romney used his song Wavin’ Flag during his Florida primary victory speech.

K’naan said Mr Romney’s campaign did not seek approval to use the song and that he would not have granted permission if it had.

The Somali-born Canadian-based rapper said he would happily grant President Barack Obama’s campaign the use of the song.

Wavin’ Flag was an international hit for K’Naan in 2010.

The song had several country-specific remixes, featuring artists from those territories and was one of official World Cup songs last year. It was co-written and co-produced by Bruno Mars’ production team, The Smeezingtons.

K’Naan says he wants to make sure Mr Romney does not use his song again.
