The Northern Ireland Assembly has failed to elect a speaker, effectively leaving the institutions suspended almost a month after the Stormont election.

The position must be filled on a cross-community basis and the DUP had already indicated it would not support the move as part of its protest over the Northern Ireland protocol.

The DUP said it will not facilitate the return of power-sharing until significant concessions are agreed between the UK and the European Union.

The assembly was recalled on foot of a Sinn Féin petition backed by the SDLP and the Alliance Party.

The failure to elect a speaker means plans to fill the Offices of First and Deputy First Ministers also had to be put back.

The DUP's position was criticised by Sinn Féin's leader in Northern Ireland Michelle O'Neill.

She said the electorate wanted "the parties and every single MLA to get their sleeves rolled up and get back to work".

She said the DUP's stand was not against the EU but against people who were crippled in pain on hospital waiting lists.

DUP MLA Paul Givan said the recall was simply a stunt and "had no credibility coming from a party who had kept the institutions down for three years."

Sinn Féin withdrew from the institutions in 2017 amid a scandal over a green energy scheme and concerns over Irish language rights.

Mr Givan said that for two years unionists had raised concerns about the protocol and been ignored.

"The time for words is over. It's action we need to see," he said.

Alliance MLA Eoin Tennyson said the public were being used as "leverage" by the DUP.

After a speaker failed to be appointed, the assembly was adjourned to a future date.
