We have a statement now from the Irish government, saying it has been following court proceedings in Belfast overnight.

It adds: "The government is monitoring the situation on the ground closely and will remain in contact with key interlocutors, including the Garvaghy Road residents.

"The government is very concerned about the situation.

"Our primary concern remains to avoid a return to the divisions of the past, recalling the significant progress made over many years in furthering reconciliation under the Good Friday Agreement."

Democratic Unionist Party (DUP) MP Carla Lockhart says First Minister Michelle O'Neill is "whipping up hysteria" at an unlawful protest.

She calls O'Neill's comments "outrageous" and the protesters a "rabble".

O'Neill, Sinn Féin President Mary Lou McDonald and other nationalist politicians are currently part of the protest blocking the Garvaghy Road.

"The law is on our side," Lockhart, MP for the Portadown area, says.

"They're afraid of 35 men, walking down a road silently."

Orangemen in Portadown are content, at this stage, to wait until the Garvaghy Road is clear.

Rather than postpone their parade, they are waiting in a hall at Drumcree Church for the go-ahead to march.

As things stand, that seems impossible. And it is unlikely to change in the coming hours.

In the 1990s, when Orangemen were prevented from marching, a long stand-off developed. Thousands of supporters gathered at Drumcree.

This morning, the 35 Orangemen are waiting alone and have not called for support on the ground.

Another difference from the 1990s is the weather. It is cold and wet. The Drumcree disputes 30 years ago were always at the height of summer in July.

There are big decisions to make for the police to make in the coming hours. One officer said in Portadown this morning “it’s a no-win situation, whatever we do”.

The Orange Order's Portadown District Master Nigel Dawson has been speaking to the media outside a hall at Drumcree Church, where they have been waiting out of the rain.

He tells Orangemen they will wait for the police to tell them the Garvaghy Road, which is currently blocked by protesters, is ready for them to parade.

"The position of the district is clear; we will abide by the police direction at all times throughout the course of today."

With the legal avenue to stop the march having been exhausted in the early hours of this morning, Sinn Féin is pushing for some last-minute political intervention.

They’ve called on Secretary of State Sir Chris Bryant to use his powers to ban the parade but there is no sign that is going to happen.

He can act if the police ask him to review the determination to prevent serious public disorder.

As yet, there has been no such request.

Meanwhile Sinn Féin’s top team are on the Garvaghy Road.

They’ve vowed to stand with the residents despite the political consequences of taking part in what is an illegal protest.

Some, including First Minister Michelle O'Neill, will be accused of breaching the ministerial code but it is clear that is not a priority for the party right now.

I'm standing at Drumcree Church, where the Orangemen have been gathering. There's a police presence here. It's raining heavily.

We can hear police announcements from the Garvaghy Road, which is about one mile away.

Each one is met by jeers from the crowd.

We can hear the crowd singing.

• "There must be no march through this community," Sinn Féin President Mary Lou McDonald told reporters as she stood with protesters this morning
• But Deputy First Minister Emma Little-Pengelly, from the Democratic Unionist Party (DUP) says "there is no violence or threat from the Orange Order" and has called for the parade to proceed

The Orange Order's planned parade - from Drumcree church on the outskirts of Portadown, down Garvaghy Road and to the town centre - is set to begin. But what is the Orange Order and why does today matter?

The Orange Order is a fraternal organisation that derives its name from William of Orange - the Protestant Dutchman who seized the throne from Catholic King James II back in the 'Glorious Revolution' of 1688.

Two years later, 'King Billy' saw off James for good at the Battle of the Boyne, a moment the Orange Order celebrate annually during Twelfth of July celebrations.

The Twelfth is the biggest day of Northern Ireland's marching season, celebrated by the Orange Order every year from April to August, when Orangemen march to commemorate William's victory.

Most lodges march with a band, and the distinctive ceremonial outfits of Orangemen include suit and tie, bowler hats, orange sashes and white gloves.

For many Catholics, these marches are considered triumphalist and sectarian, with some traditional Orange routes passing through or by staunchly Catholic and nationalist areas.

Of all the routes, the Garvaghy Road route is perhaps the most contentious of all.

Sinn Féin President Mary Lou McDonald is on the Garvaghy Road in Portadown along with party colleague First Minister Michelle O'Neill.

McDonald is the party's leader across the island of Ireland, while O'Neill leads Northern Ireland's devolved government as first minister.

"There must be no march through this community. That is how we restore calm, that is how we restore confidence," says O'Neill.

"This is primitive stuff in the year 2026."

O'Neill asks: "Why after 28 years of determination to block a march down this road that the Parades Commission thought this was the right idea today? To bring this mess back onto this community."

"I commend this community. We stand with this community and we will continue to stand with this community."

This map shows the route the Orange Order are due to walk this morning, from Drumcree Church on the outskirts on Portadown, County Armagh.

It takes them from Drumcree to Carleton Street Orange Hall via the Garvaghy Road.

Right now, the Garvaghy Road has been blocked by protesters, while Orangemen are gathered at Drumcree Church waiting to get the march under way.

Just before 08:00, 30 Orangemen gathered outside Drumcree Church.

A police bronze commander then radioed his team and asked if the route was clear for them.

After a few minutes, he informed the Orangemen that the road was not clear.

They have returned to their hall, to avoid the rain, as they await a police determination that the road is clear.

Orangemen have begun lining up at Drumcree Church ahead of a planned parade in a few minutes for the mile-long walk, which takes in the Garvaghy Road and ends at the Orange Hall at Carleton Street.

The Parades Commission, which decided the march could go ahead, put restrictions on the event, saying no more than 35 people and no bands were allowed to take part.

The Garvaghy Road is currently blocked by protesters.

The focus of decision-making has been passed from the Parades Commission to the High Court to the police.

Senior officers will have to determine whether the march can go ahead or not, for security reasons.

As things stand, there is no clear path down the Garvaghy Road as protesters are blocking it.

The march is due to begin very soon - just before 8am - from Drumcree Church.

Decision time is approaching for the police.

Northern Ireland Secretary of State Sir Chris Bryant is coming under pressure from Sinn Féin to ban the Orange Order parade along the Garvaghy Road.

It’s understood First Minister Michelle O’Neill has asked him to intervene after the courts rejected a bid by residents to stop the march in the early hours of this morning.

The secretary of state has the power to act against the parade if police have concerns about serious public disorder.

Under public procession legislation, the secretary of state can revoke a decision by the Parades Commission - the body that rules on marches and parades in Northern Ireland - but only if he is asked to review the decision by Northern Ireland's chief constable.

This could happen if police are concerned about serious public disorder.

There has been no official response from the secretary of state or Northern Ireland Office.But it’s understood as yet the PSNI has not asked the secretary of state to review the determination.

The first and deputy first ministers of Northern Ireland have both appealed for calm ahead of this morning's Orange Order parade.

First Minister Michelle O'Neill, from nationalist party Sinn Féin, and Deputy First Minister Emma Little-Pengelly, from unionist party the Democratic Unionist Party (DUP), have different views on whether the march should go ahead - O'Neill opposes it, while Little-Pengelly supports it.

O'Neill, speaking on X, said Garvaghy Road residents were "completely horrified" and that she supported the "protest against this unwanted sectarian march".

However she also said she was "calling for calm on all sides".

Little-Pengally, in a social media statement, said she wanted to "appeal for calm and leadership" and said there is "no violence or threat from the Orange Order".

The Police Service of Northern Ireland (PSNI) are warning people gathering on the Garvaghy Road that their protest is illegal, as Ireland correspondent Chris Page reports above.

There's a large group of people on the road in Portadown this morning, ahead of the planned parade.

Some are carrying banners and posters. There's a large police presence.
