DUP minister Edwin Poots has warned the impasse over Brexit's Northern Ireland Protocol could lead to the "funeral of the Good Friday Agreement".
And DUP MP Ian Paisley said changes to the government's Westminster bill aimed at overriding the Irish Sea trading arrangements would mean "devolution never returns to Northern Ireland".
The senior party figures launched a renewed attack on the protocol as talks are due to resume between the UK and European Union in the latest attempt to resolve the impasse.
