Polands foreign ministry on Thursday said it objected to a visit by US white supremacist Richard Spencer, whom Polish nationalists have invited to an Independence Day event next month.
Spencer is the 39-year-old leader of the so-called "alt-right" movement -- encompassing white supremacists, neo-Nazis and the Ku Klux Klan -- and the organiser of a white supremacist rally that erupted in deadly violence in Charlottesville, Virginia earlier this year.
