Brexit leader said victory came without a bullet being fired. He seems to have forgotten Jo Cox.

Last week, ahead of Britain's epochal referendum over whether it should leave or remain in the European Union, a leading politician was killed while on the campaign trail.

Jo Cox, a rising star in the Labour Party and a mother of two young children, had been seeking votes for the "remain" camp. The assailant who stabbed and shot her is believed to have a long history of affiliation with neo-Nazi and white supremacist organizations. Appearing before a magistrate, he said his name was "death to traitors, freedom for Britain."
