Another orange and green election row as DUP warn Sinn Fein over Irish language #BBCNolan #AE17

Another day and another row between the DUP and Sinn Fein - this time over the Irish Language. As Arlene Foster launched the DUP's election campaign yesterday she gave a blistering warning to her political rivals. Sinn Fein leader Michelle O'Neill said she wouldn't get drawn into a war of words, while Gerry Adams poked fun at the outburst. The row comes a matter of weeks after Edwin Poots and Conor Murphy argued on this programme over whether an Irish Language Act was part of the St Andrew's Agreement. It's another green and orange issue that the two parties are at complete odds over. What impact could these sort of spats have if the two are to share power again after the election? Stephen talks to former Sinn Fein MLA Daithi McKay, DUP's Nelson McCausland and SDLP's Patsy McGlone.
