Sinn Féin, SDLP, Alliance and NI Greens MLAs appeal over backstop in letter to Donald Tusk

A letter has been sent to Donald Tusk by a number of our local political parties urging him to continue "defending" the backstop in the face of Boris Johnson's latest calls for it to be scrapped. In a joint letter to the European Council chief, Stormont's pro-Remain parties said the mechanism was "necessary" to safeguard the progress made since the signing of the Good Friday Agreement. But the DUP has said that it shows that the backstop doesn't have unionist support. Stephen got the views of DUP MLA Jim Wells and Alliance MLA Stephen Farry.
