ARLENE FOSTER’S resignation and the infighting in her Democratic Unionist Party (DUP) show that “partition has failed — it has run its course,” the Communist Party of Ireland (CPI) declared today. General secretary Eugene McCartan said that “after 100 years of partition, unionism has finally run out of options and unionists’ relationship with the British state has been downgraded. “The British have courted and secured new forces to advance their imperial interests in Ireland, north and south. “It’s not just Brexit that has accentuated the ongoing and deepening crisis within unionism. Political unionism has little, if anything, to offer its working-class base, other than the relentless dog whistle of sectarianism.”
