Politicians in Northern Ireland have once again failed to elect a Stormont speaker
It is the seventh recall of the assembly since May 2022
The assembly collapsed in early 2022 due to the Democratic Unionist Party's (DUP) protest over post-Brexit trade rules for NI
It has not been able to sit since as the DUP has refused to vote for a speaker
The DUP's veto on Stormont means no other assembly business can take place

Today's Stormont recall could be the last sitting of the assembly if the DUP refuses to end its boycott, Sinn Fein warns.
Vice-president Michelle O'Neill also questioned the DUP's motives and said the "only remaining explanation... is the refusal to accept a nationalist first minister".
The SDLP's proposal for speaker is Patsy McGlone.
He is proposed by Matthew O'Toole and seconded by Cara Hunter.
Business is now underway in the chamber.
The UUP's John Stewart proposes Mike Nesbitt as speaker.
Mr Nesbitt says he is "very, very happy" to accept the proposal.

If at first you don't succeed, try and try again.
The problem is that saying hasn't quite worked out so far for those politicians hoping to be back on Stormont's blue benches by now.
Today's events are already expected to return the same outcome as the past six recalls, with our politics remaining as frozen as the winter weather this week.

We already know he's refused to release the cash for public sector workers in time to avoid Thursday's mass strikes.
But with the government's repeated failed attempts to make Plan A successful, the focus is switching to its Plan B - whatever that looks like.

Ulster Unionist Party (UUP) leader Doug Beattie says he anticipates that his fellow members will "vent their frustrations at what has happened over the last two years" when they get into the chamber.
But he adds that the end result will be the same as before.
"We will not have Speaker, we will not a first or deputy first minister, we will not have government up and running," he tells gathered reporters.
"That is a failing - and it's a failing of all politicians.
"We have failed to deal with the issues in front of us, to get a executive up and running and it will be people who will suffer.
"Standing here, I am even more pessimistic than I was this time last month - last month there was an opportunity and now I think it's gone.
"I don't see Stormont back up and running any time soon.
"I hope I'm wrong but I just can't see it."

Without a new speaker in place, that role falls to the Father of the House, Ulster Unionist MLA Alan Chambers.
He's the oldest MLA present not seeking election as peaker.
It falls to him to call members from each party to speak.

The DUP has been blocking the restoration of Stormont's power-sharing institutions since 2022 in protest against post-Brexit trade checks between Northern Ireland and Great Britain.
It believes the arrangements under the Northern Ireland Protocol diminish the region's place within the UK internal market.
A new deal, called the Windsor Framework, aimed at addressing those concerns was agreed in February 2023 between the government and European Union.
But the DUP said this did not go far enough, and for months the party has been in talks with the government seeking further changes.
If no executive is formed by Thursday, the Northern Ireland secretary is under a legal duty to call an early assembly election.
But Chris Heaton-Harris has already pushed this deadline back several times before and has indicated he may do so again.
There have been six previous recalls of the assembly since May 2022.
Every time there has been a vote to elect a speaker, the Democratic Unionist Party (DUP) has blocked the move.
The party's veto, which is unlikely to change, means no other assembly business can take place.

The latest legal deadline for the assembly to be restored coincides with a mass strike involving thousands of public sector workers calling for better pay and conditions.
On Monday, Stormont Speaker Alex Maskey confirmed that 30 signatures had been received - the number required for a recall petition to succeed.
He said the assembly was being recalled to elect his successor and appoint first and deputy first ministers.
If the executive is not restored by Thursday, fresh elections are required.

After a night of sub-zero temperatures, will MLAs remain frozen out of Stormont or could there be a thaw in relationships to reboot the assembly?
We will bring you all the latest as another attempt is made to elect a speaker.
The sitting begins at 12:00 GMT following a successful recall by Sinn Féin.
