"Yellowhammer", as we heard yesterday, the secret Whitehall dossier leaked to the Sunday Times suggests the government and the UK are 'hugely unprepared for a No Deal Brexit'. Among other things it warns of medicines shortages, but the PM's policy advisor and cabinet minister in charge of preparing for a No Deal Brexit - Michael Gove - says the report "is a worst case scenario" and very significant steps have been taken to accelerate Brexit planning. The DUP have also described the dossier as 'outdated'. We talk on this programme about protecting the 'vulnerable'. So just how concerned should we be when we hear of possible shortages in medicine? Stephen spoke to Dr Tom Black, chair of the British Medical Association (BMA) Northern Ireland, Simon Wigglesworth - Deputy Chief Executive of Epilepsy Action - and Terry Maguire is a pharmacist from the Ulster Chemist Association.
