(Part 2) Stormont in crisis as Executive collapses - where do we go from here? #NolanRHI

Stormont's Fresh Start came to a shuddering stop as the resignation Martin McGuinness collapsed the Executive yesterday. The split between the DUP and Sinn Fein has turned toxic with the two parties trading insults with each other in the fallout over the Cash For Ash scandal. A snap election is looming but Mr McGuinness has warned there can be "no return to the status quo". The bitter spat between the two parties was clear when two of their ministers, the DUP's Paul Givan and Máirtín Ó Muilleoir of Sinn Fein spoke to BBC's Tara Mills last night. What next for Stormont now? Stephen talks to DUP MP Gregory Campbell and Sinn Fein MLA Conor Murphy.
