One of the people taking part in the procession is Jackie Sheridan.

Her great-great-uncle Oliver Davies was a driver for the Royal Engineers and died aged 21 in 1917 near Jerusalem. He was killed by a stray bullet as he took animals to get some water.

Mrs Sheridan said it was a "very proud moment to represent my family who are descendants".

"It's going to be emotional to see everybody here, knowing there's 10,000 of us," she said.

She wiped away tears as she spoke about a Land Army badge she was wearing that belonged to her grandmother. "That was very important to her," she said.

The parade passes the Women in War memorial on Whitehall - a poignant moment.

The memorial is dedicated to the seven million women who worked in World War Two.

The parade passes Nelson's Column where jubilant Londoners lit a bonfire on Armistice Day, exactly 100 years ago.

"I feel so privileged to be here," says Jane Harman, who discovered the first soldier to die in World War One had been a former pupil of the primary school where she worked.

John Parr, a north Finchley boy, was 17 when he died two days before the start of the Battle of Mons.

It was 21 August 1914, but it was to be another eight months before his mother found out he had died.

In a heartbreaking letter to the War Office, sent in October 1914, she wrote: "I'm very anxious as it's now 10 weeks."

Jane, who now teaches at Norfolk House in Muswell Hill, has been telling his story to children in school assemblies.

"What I've found heartwarming is how respectful all the children were - even children as young as six," she says.

Michael D Higgins, Ireland's president-elect, has attended the Armistice Day centenary commemorations at Dublin's Glasnevin Cemetery.

He paid tribute to those who fought in World War One, in particular the 200,000 Irish men who served and those who died overseas.

"Ours is not a celebration of militarism, nor a valorisation of martial spirit, but a simple recognition of our common humanity, as we recall the destruction of the promise and potential of a generation."

It comes hours before Mr Higgins is to be inaugurated for his second term as president of Ireland.

A procession of 10,000 people to the Cenotaph is taking place this afternoon to honour those who died in WW1.

Members of the public were given the unique opportunity to join a procession past the Cenotaph in London by entering a ballot.

The so-called People's Procession has not taken place before, and 10,000 members of the public have been selected at random to take part.

The procession itself will take around 30 minutes and will start at Green Park, before heading past the Cenotaph and finishing at St James’ Park.

Participants will be able to lay a wreath at the Cenotaph as they file past.

They will march together to pay their respects and help express the nations thanks to the generation that served and those that never returned.

Our reporter, Marie Jackson, who is with the march, says:

"We're parading past Trafalgar Square, where exactly 100 years ago to the hour, crowds were amassing.

"Four years of bloody and bitter battles were over, and the country's men were coming home.

"In celebration, the crowds climbed on to the lions in the square and lit a bonfire under Nelson's Column."

Thousands of paper poppies were dropped from the central tower of Truro Cathedral in Cornwall to mark Armistice Day.

The flowers rained down on those attending the church's remembrance service.

In towns and cities across the UK, bells rang out at 12:30 GMT.

The extraordinary event was led by Big Ben in London, before bell ringers in churches and cathedrals all over the country followed suit, symbolising the end of World War One.

The Pope addresses crowds at Saint Peter's Square at the Vatican to commemorate the centenary of the Armistice.

Appearing in the window of the Papal apartments, he says: "World War One is a severe warning for everyone to reject the culture of war and to seek every legitimate means to put an end to the conflicts that still plague many regions of the world.

"Let's invest in peace, not war."

Church bells at St Peter's Basilica are set to ring out at 13:30 local time (12:30 GMT) to commemorate the centenary.

Under the Menin Gate in Ypres, Belgium, thousands of people have marched along the route once taken to the trenches.

Military units, veterans, families and faith communities attended.

Many carried wreaths to lay under the great arch which remembers the 55,000 officers and men from Britain and the Commonwealth whose remains were never identified .

While Armistice Day marks 100 years since the end of WWI, it honours all of those who have lost their lives in conflict.

Ken joined the army in 2005 when he was 17. He served on three tours in Iraq and Afghanistan before an IED took out his right eye and ended his military career.

He said: "For me, it is so important to march here every year.

"I’m here to pay my respects to those soldiers who have given the biggest sacrifice to this nation, I will always remember them."

York Minster’s Five Sisters Window is the only memorial in the country dedicated to all women of the British Empire who lost their lives during World War One, according to officials.

The window, which dates from the mid-1200s, was restored and rededicated between 1923 and 1925 after it was removed to protect it during Zeppelin raids.

Thousands of people in communities the length and breadth of the UK observed a two-minute silence at 11:00 GMT in recognition of the centenary of the Armistice at ceremonies, parades and services.

In Scotland, first minister Nicola Sturgeon laid a wreath at the Stone of Remembrance outside the city chambers in Edinburgh after 11 rounds were fired from the castle.

In Northern Ireland, the largest event took place at Belfast City Hall, attended by the Northern Ireland secretary and Ireland's deputy prime minister.

And in Wales, first minister Carwyn Jones took part in a ceremony at Cardiff's war memorial ahead of a service with Prince Edward and the Countess of Wessex, at Llandaff Cathedral, Cardiff.

Across the country, 100 beacons of light were lit, symbolising an end to the darkness of war and a return to the light of peace.

The Mall is now packed with people proud to remember the part their family played in the war.

Dressed in the sombre, dark clothes of remembrance, many wear an ancestor's solitary medal, others row upon row, alongside their poppies.

They carry wreaths with carefully crafted messages of thanks and speak of their pride in their grandfathers, great-grandfathers and great uncles.

It's already been a morning of emotions - pinning on the medals, sharing their stories - but the parade will be when the tears are shed.

Robert Malin was working at St Pancras Hotel when war was declared.

At 27, he was sent to the front and made a bearer - it was his job to send in the stretchers and carry away the wounded.

But he went beyond the call of duty, says his grandson Jeremy Cripps, 64, from South Shields.

In the Battle of Amiens in France, in the last 100 days of war, Robert Malin went out under fire many times to bring back the wounded.

Among them was an officer, Raymond Trustram, who made it out but died later from his injuries.

Jeremy Cripps has an extraordinary letter of thanks from the officer's father, commending Robert Malin for his "gallant act" and inviting him to visit.

Today, Mr Cripps will walk in the parade with his wife, Carol, and daughter, Jessica, wearing his grandfather's medals for bravery.

"Wearing these medals makes me feel emotional," he says.
