LONDON (Reuters) - British Prime Minister Tony Blair has agreed to meet representatives of Protestant „Orangemen“ who are involved in a standoff with security forces over a banned parade in Portadown, Northern Ireland, the BBC said on Tuesday. But it said Blair would not reopen the decision of the province‘s independent parades commission to bar the Orange Order, a pro-British brotherhood founded two centuries ago, from marching down the mainly Catholic Garvaghy Road. Thousands of Orangemen have been camped out at Drumcree near Portadown since Sunday when security forces prevented them from walking their traditional route, which they have used every year since 1807. The standoff has triggered violence across Northern Ireland for the past two nights, casting a pall over efforts to bring peace to the British-ruled province after three decades of sectarian and political violence that claimed 3,600 lives.
