Seamus Mallon 'sad and angry' at state of politics in Northern Ireland

One of the architects of the Good Friday Agreement has said he is sad and angry at how politics in Northern Ireland sits 20 years after the landmark deal.
Former SDLP deputy first minister Seamus Mallon, who helped broker the 1998 peace accord, has accused the Democratic Unionists and Sinn Fein of creating political silos, debasing the process and "almost Balkanising" the country.
