The World Jewish Congress has said it is deeply disturbed by the Polish government's failure to act and remove an anti-Semitic banner hung on the gate of a guesthouse barring Jews from entering.

This scumbag has got a long list of form for racism, recently being sentenced to prison for burning an effigy of an orthodox Jew during a neo-Nazi rally in Wroclaw (or should that be Breslau, given the Nazi motifs of the rally). His criminal past is so bad that he's even banned from entering the UK!
