No devolved government. No direct rule. And High Court casts doubt over whether civil servants can take key decisions here in the future. So who is in charge of NI? @columeastwood

Northern Ireland has been in political limbo for the last 16 months. We've no functioning devolved government. We also have no direct rule from London. Senior civil servants have been doing their best to keep the country running. But can that continue? Yesterday, a controversial incinerator in Mallusk was blocked by the High Court. Planning permission for the multi million pound facility was approved by a Department for Infrastructure civil servant last year. It caused controversy as politicians argued it was not his decision to take. And the High Court has agreed. It ruled that senior civil servant, Peter May, had no power to approve the planning application. So, this is question we're asking this morning - who is in charge now in Northern Ireland? Vinny spoek to our Political Editor Mark Devenport and SDLP leader Colum Eastwood.
