The DUP has been challenged by Stormont opponents for "cherry-picking" a health report to support its criticisms of Brexit's Northern Ireland Protocol.
Sir Jeffrey Donaldson's party issued a statement saying the think-tank paper was "further confirmation" that the protocol is "disrupting" medicine supplies to Northern Ireland.
But the DUP did not mention that the Nuffield Trust report concludes Brexit itself is having "negative effects" on the UK's workforce, medicines and economy.
