The Democratic Unionist Party ( DUP) MP for Upper Bann, Carla Lockhart, calls on the Police Service of Northern Ireland (PSNI) to "do their job" and police the determination of the Parades Commission.

"I remind everyone that it is 35 men with a collarette, with no bands, walking silently down a road," she says.

"That stands in stark contrast to the rabble that is positioning themselves on the Garvaghy Road and blocking the road."

"Our message is loud and clear," Lockhart continues.

"The Portadown District have a lawful determination, and it is now for the police to police it."

Social Democratic and Labour Party (SDLP) leader Claire Hanna arrives at the Garvaghy Road, where she says: "We are in a stand off here and it is necessary to deescalate."

Hanna is calling on the chief constable and secretary of state to intervene, saying she had reminded both they have the "ability to revoke any permission for this parade".

"Whatever the legalities, it was never politically right or morally right to do this," she says.

Hanna says the march is a "violation of this community who just want to live in peace" and argues "that it is how it is being viewed far beyond this road".

Loyalist activist Jamie Bryson says Sinn Féin's behaviour is "absolutely scandalous".

"Today, they are blocking the road. They are defying the court," he says.

He adds there is an onus on the PSNI to ensure the law is upheld, adding the Portadown District "will not be going anywhere" until they can complete their path down the Garvaghy road.

Bryson adds that there's "no disruption from this community", saying: "Let it be very, very clear...if there is any notion that the unionist people of the Portadown District are going to walk away with the tail between their legs, having been bullied by Sinn Féin, let me disabuse you of that."

He appeals for people to stay calm and not get "drawn into any provocation or disorder".

A large security operation is under way across Portadown.

Many roads are closed in the town.

A short time ago the DUP's Carla Lockhart and Jonathan Buckley held a press conferences at the opposite end of the Garvaghy Road to protesters.

Hundreds of supporters stood in heavy rain as they spoke. Others took shelter under a bridge.

Meanwhile police are operating a sterile zone under the town's railway bridge which crosses over the Garvaghy Road, to keep the two sides apart.

Even the broadest umbrellas and most tightly pulled hoods are struggling to keep heads dry in Portadown now, on what is a miserable morning weather-wise.

Protesters on the Garvaghy Road say they shall not be moved.

A mile away, outside Drumcree Church on rural outskirts of town, Orangemen and their supporters remain steadfast that the parade will go ahead.

On both sides, the rain continues to come down.

As it stands, the person with the power to intervene in this impasse is Northern Ireland Secretary Sir Chris Bryant.

He's cutting short his attendance at the Labour Party Conference in Liverpool to travel back to Belfast.

Sir Chris could order that the march cannot go ahead - but he can only intervene if asked to by Police Service of Northern Ireland (PSNI) Chief Constable Jon Boutcher on the basis that it would prevent serious public disorder.

And Sir Chris has told the BBC that the head of Northern Ireland's police hasn't asked him to do that yet.

Meanwhile, the situation on the Garvaghy Road hasn't changed.

Orangemen await further instruction from the police to indicate when the road is clear for them to march. Protesters continue to block the route of the parade and say they're going nowhere.

And the rain continues to fall over Drumcree Church.

The deputy leader of the Alliance Party, Eóin Tennyson, says people are in "utter despair that this is where we are as a society this morning".

The Alliance Party is the third biggest party in Northern Ireland and does not consider itself as either nationalist or unionist.

"Reopening the Pandora’s box of Drumcree has only caused huge hurt and has raised tensions to a level not seen in years." says Tennyson.

"We cannot relive the past. We must be capable of learning from it and finding a way to move forward together.

"Our utmost priority must be the safety of all concerned. I am again appealing for calm, restraint and cool heads on all sides."

Police Service of Northern Ireland (PSNI) chief constable Jon Boutcher says the police operation so far has "helped ensure there has been no violence or disorder".

"I'm unbelievably proud of my officers who, supported by mutual aid colleagues, are managing an exceptionally challenging situation," he says.

"We have an evidence gathering operation in place to detect any offences and will continue to do this throughout today."I appeal to everyone to remain calm and peaceful. I am immensely grateful for all those voices who have already called for calm."

He urges everyone "with influence to encourage people to comply with the law" and says the police are engaging "with all parties".

"It is incumbent on us all to come together at times like this to do all we can to preserve a peaceful Northern Ireland."

On Friday evening, the PSNI said it had activated "mutual aid arrangements", with it being understood 200 officers were arriving from Scotland to help with policing this morning.

Breandán Mac Cionnaith from the Garvaghy Road Residents' Association says the only thing the community can do to stop the march is to "keep mobilising".

"We have made it clear through petitions to the Parades Commission and others this community never wanted this march.

"That was ignored."

He says the protest will last "as long as it takes".

We understand there's to be a DUP press conference in Portadown shortly but, in the meantime, we have a statement from party leader Gavin Robinson.

Echoing other unionist voices we've heard this morning, he's calling on First Minister Michelle O'Neill "to uphold lawful decisions, not inflame opposition to them".

“The legal position is now unequivocal - 35 Orangemen can walk in silence along Garvaghy Road.

"The Court of Appeal found that the injunction had been granted in error, and the High Court subsequently confirmed that the Parades Commission determination must be respected."

Robinson says "the rule of law cannot apply only when Sinn Fein likes the outcome", and commends "the Orangemen of Portadown" who he says "have conducted themselves with dignity and respect for the rule of law for 28 years".

Here's the latest this morning:

• The Orange Order was due to set off on its march from Drumcree Church, which would take it down the mainly nationalist Garvaghy Road in Portadown, at 08:00
• However the parade has not set off yet and is delayed - the Garvaghy Road has been blocked by hundreds of protesters, while Orangemen who have gathered at Drumcree, a mile from the road, have said they will wait until police advise them the road is clear
• Police have called on protesters to disperse but there is no indication that will happen
• Sinn Féin leaders, including First Minister Michelle O'Neill, are among the protesters at Garvaghy Road, with O'Neill saying the dispute "brings into question how the peace process works"
• However Democratic Unionist Party (DUP) MP Carla Lockhart has criticised O'Neill for "whipping up hysteria"

• Northern Ireland Secretary Sir Chris Bryant is travelling back to Belfast from the Labour Party conference, while Prime Minister Andy Burnham has appealed for calm

Northern Ireland Secretary Sir Chris Bryant says he's cutting short his attendance at the Labour Party conference to return to Northern Ireland, adding that he's taking the situation "very, very seriously".

He says a court decided that the Parades Commission determination stood, adding that "it's important that everybody abides by the law".

Speaking to BBC News NI at the conference in Liverpool, he urges calm and says any protest is "unlawful" and police have "made that clear to people".

"I would urge people to cooperate with the police. I would say that on both sides incidentally."

He says it's "primarily a policing matter" and he can only act if asked to by the chief constable and he "hasn't asked me to do so".

Northern Ireland First Minister Michelle O'Neill, who is among the protesters on Garvaghy Road, says the reignition of the Drumcree dispute “brings into question how this whole peace process works”.

Some in the crowd blocking the Garvaghy Road this morning have been heard shouting “bring Stormont down” while O'Neill says there are those in "Orange Order and those within political unionism that want to drag us backwards".

Stormont - Northern Ireland's devolved government - has existed for almost 30 years as a power-sharing arrangement between the largest nationalist and unionist parties. It has collapsed several times over the decades when one side or the other has withdrawn from government.

The last time it happened was February 2022 with it taking about two years before the institutions were up and running again.

Asked if the power-sharing could collapse, O'Neill says: “You heard it about the people’s view of Stormont. You heard it about the terms of politics working for them, and you hear it here time and time again and we’ve certainly heard it over the last 24 hours.

“What’s the point? What’s the point whenever people are going to railroad over their rights? Whenever they’re going to try to roll back in 28 years of progress?

“But I can tell you what we’re about. We’re about the future. We’re about building on our peace and progress. We’re about not allowing people to bring us back.”

A large crowd is still on the Garvaghy Road in Portadown with protesters linking arms.

People who are standing along the side of the road are being urged to move to the centre of the crowd.

The People Before Profit (PBP) assembly member, Gerry Carroll, has joined other politicians at the gathering.

The Orange Order are still at a hall at Drumcree Church, about a mile from the road, awaiting further instruction from the police. The parade was due to set off almost two hours ago.

The Prime Minister says he has spoken to Northern Ireland Secretary Chris Bryant this morning and Taoiseach (Irish Prime Minister) Micheál Martin yesterday.

"I know it's a tense situation and we appeal for calm on all sides," Andy Burnham tells Sunday with Laura Kuenssberg.

"There have been big gains made in Northern Ireland and we don't want to see things go backwards."

The leader of the Social Democratic and Labour Party (SDLP), Northern Ireland's second largest nationalist party, Claire Hanna has also arrived on the Garvaghy Road in Portadown.

In a social media post on X, she says she's “standing in solidarity with local residents”.

“Allowing this parade to proceed violates the rights of people who live here. They must see sense and stop it.”

The story of today's march is mainly taking place across two locations in Portadown - the Garvaghy Road, where protesters have blocked the road; and Drumcree Church, a mile to the west, where Orangemen and supporters have gathered for the march to get under way.

Unionist politicians and campaigners are also at the church, with one activist - Jamie Bryson - heavily criticising the "so-called first minister for all" for "illegally blocking" the road.

Bryson says "there are now serious questions for Sinn Féin about their commitment to the law".

Jonathan Buckley, of the Democratic Unionist Party (DUP), says "the court had its say" and "the law shall prevail".

"For 28 years, Sinn Féin and Garvaghy Road residents have told Portadown district (Orange Order) and the wider unionist community that the Parades Commission has reached its determination, people should abide by the law," he says.

The Democratic Unionist Party (DUP) and Sinn Fein are in the power-sharing devolved government at Stormont.

They are the two biggest parties; in effect they run Northern Ireland together.

But this issue has certainly laid bare the political divisions that still exist here; Sinn Féin and the DUP see this issue in completely different terms.

Northern Ireland is still a place where symbols, territory and identity really matter.

There's really no meeting of minds on this - save for First Minister Michelle O'Neill and Deputy First Minister Emma Little-Pengelly both calling for calm.
