The DUP had threatened to stop the Northern Ireland Assembly from working, in protest at post-Brexit trade protocol, and that happened today.
Members were registering after last week’s election gave Sinn Féin the lion’s share of seats.
For the speaker to be sworn in and for the assembly to function, the DUP’s participation would be required, but its leader, Sir Jeffrey Donaldson, would not allow it.
Sinn Féin leader Michelle O’Neill accused him of “denying democracy” and Northern Ireland secretary Brandon Lewis called on the parties to unite.
