Prince Harry arrived at Clarence House today for what is expected to be a long-awaited reconciliation meeting with his estranged father King Charles III.

The Duke of Sussex was spotted being driven into the royal residence for their first face-to-face meeting in more than a year and a half since Harry made a transatlantic dash to see the monarch in February 2024 after hearing of his cancer diagnosis.

Earlier, the King was seen arriving at Clarence House at 4pm, having landed at RAF Northolt in West London around 3pm following a flight from Aberdeen Airport.

His 40-year-old son Harry had been in White City this afternoon touring Imperial College London's Centre for Blast Injury Studies in a visit that ended just after 3pm. He was seen being driven into Clarence House at 5:20pm. 

The head of state had flown to the capital after a stay at Balmoral in Aberdeenshire, raising the possibility of a meeting with Harry during his son's four-day stay in Britain.

Later today, the Duke will be at a reception event linked to the Invictus Games, which he launched in 2014 as a tournament for injured service personnel and veterans.

Harry had about three hours spare for a meeting with Charles between his two engagements in London this afternoon, and will have further time tomorrow morning before attending another final event ahead of his flight back to California.

The Duke is three days into a rare four-day trip to the UK, carrying out a string of solo charity visits, but until today had not seen the King or his brother William.

Harry arrived in Britain on Monday and attended the WellChild Awards at London's Royal Lancaster Hotel to celebrate the achievements of seriously ill youngsters.

He then travelled by car to Nottingham yesterday to visit the Community Recording Studio and announce a £1.1million personal donation to the BBC's Children In Need.

This afternoon, Harry was all smiles as he was greeted at the Centre for Blast Injury Studies in White City at about 1pm and hugged former Army captain David Henson.

The ex-Royal Engineer served as Team GB captain for the inaugural Invictus Games and attended Harry's wedding to Meghan Markle at Windsor Castle in 2018.

Mr Henson lost both his legs above the knee after standing on an improvised explosive device in 2011 while clearing a compound in Afghanistan. He went on to gain a PhD in Amputee Biomechanics at Imperial.

Harry opened the Centre for Blast Injury Studies in 2013, which was the forerunner of Imperial's new centre which was launched a few years ago on its White City campus.

Clinically-driven trauma injury research is carried out at the building, and the King visited in February to highlight support for injured soldiers in Ukraine.

Harry's office said today that his foundation has donated $500,000 (£370,000) to projects supporting injured children from Gaza and Ukraine, including helping the World Health Organization with evacuations and work developing prosthetics.

Today, the Duke visited the centre to learn more about its work, especially an increased focus on injuries suffered by children and those sustained in natural disasters.

'No single organisation can solve this alone,' Harry said in a statement. 'Gaza now has the highest density of child amputees in the world and in history.

'It takes partnerships across government, science, medicine, humanitarian response and advocacy to ensure children survive and can recover after blast injuries.'

The three grants announced by Harry and Meghan's Archewell Foundation include $200,000 (£150,000) to the World Health Organization to support medical evacuations from Gaza to Jordan, and $150,000 (£110,000) to Save the Children to provide ongoing humanitarian support in Gaza.

The third grant $150,000 (£110,000) was to the Centre of Blast Injury Studies to help its efforts to develop prostheses that can support injured children, particularly those children injured from the conflicts in Ukraine and Gaza.

The Duke has a long association with the Centre for Blast Injury Studies, which was set up with a focus on helping military veterans and personnel, having opened its former laboratories in 2013.

'We very much consider you part of our story,' Emily Mayhew, the paediatric blast injury lead at Imperial College London, told him when he arrived.

The Prince himself spent 10 years in the British military, during which he served two tours in Afghanistan.

He has made campaigning to help the fate of veterans one of his main priorities, founding the Invictus Games for military personnel wounded in action.

He was joined by WHO chief Tedros Adhanom Ghebreyes for a tour of the centre, where he met with research teams working on a number of world-leading projects.

Showing him round was double leg amputee Dave Henson, an ambassador for the centre, who has known Harry for more than a decade and was the first captain of the British Invictus team in 2014.

'It's been hugely important for raising the profile of the centre,' Mr Henson, who lost his legs in an explosion in Afghanistan in 2011, said of Harry's involvement.

The centre said children were seven times more likely to die from blast injuries than adults and in 2023 with support from Save the Children began expanding its work to launch of the Centre for Paediatric Blast Injury Studies.

Among the research Harry was shown were new designs for prosthetic knee joints for children, a demonstration of the world's most advanced foot and ankle physiological simulator, and the 'gait lab' which uses a virtual environment with motion capture cameras and a treadmill to evaluate the impact of new prosthetic designs on patients.

'Here's a good looking man,' Harry said with a big grin when he saw Steve Arnold who was demonstrating the gait lab equipment.

Like Mr Henson, Mr Arnold, who lost both his legs in an IED blast ion Afghanistan in 2011, was also well known to the Duke after taking part in the 2014 and 2017 Invictus Games as a cyclist.

'It's massive help,' Mr Arnold said of Harry's visit, saying it would hopefully ensure that children and others got the same level of support he had received over the 14 years and 'get better with whatever disability they have'.

Meanwhile Harry - on the penultimate day of his UK trip - was 150 miles away from his brother Prince William today, who headed to Cardiff to see a new mental health hub.

William arrived in Wales at 12.20pm at the Principality Stadium on World Suicide Prevention Day to see the hub. 

It is being launched by the Jac Lewis Foundation, set up in the name of a footballer who took his own life aged 27 in February 2019.

The Duke's visit has re-ignited commentary about the state of his relationship with senior members of the Royal Family.

He remains estranged from William who was at Spiral Skills in Lambeth in South London yesterday promoting his Homewards project, an initiative that aims to find a blueprint to ending homelessness, with no prospect of the two meeting.

On Monday, Harry marked the third anniversary of Queen Elizabeth II's death by privately laying flowers at her grave in St George's Chapel, Windsor Castle.

But he remained apart from William, with the Prince just seven miles away visiting a Women's Institute branch in Sunningdale, Berkshire, in his grandmother's honour.

Harry and Charles last met face to face more than a year and a half ago when the duke made a transatlantic dash to see the monarch in February 2024 after hearing of his cancer diagnosis, but they spent just over 30 minutes together before the King left to recuperate in Sandringham. 

The Duke, who stepped down as a senior working royal along with his wife Meghan Markle in 2020, does not carry out official royal duties on behalf of the monarchy and remains estranged from much of the Royal Family.

Harry claimed in his controversial memoir, Spare, that William had physically attacked him in a row over Meghan, and that his brother and Kate encouraged him to wear a Nazi uniform to a fancy dress party in 2005 and 'howled' with laughter when they saw it.

The Duke - who levelled other accusations at William, Kate and the King and Queen Camilla in his Oprah interview, Netflix documentary and his autobiography - told the BBC in May that Charles will not speak to him because of his court battle over his security, and he does not know 'how much longer my father has'.

Harry is reported to have not been offered a place at a royal palace and is said to be staying at a hotel at his own expense.

The Duke has previously spoken of his hopes for a 'reconciliation' with his family, saying: 'Of course, some members of my family will never forgive me for writing a book. Of course, they will never forgive me for lots of things.'

He added: 'But you know, I would love reconciliation with my family,' and said there was 'no point in continuing to fight anymore'.

Senior aides to the King and the duke were pictured together in London this July in what was reported to be an initial step towards opening channels of communication between the two sides.

As for William today, he visited a new mental health hub in Cardiff on World Suicide Prevention Day.

William attended the Principality Stadium to see a new centre for the Jac Lewis Foundation.

Mr Lewis, a popular footballer from Ammanford, was aged 27 when he died by suicide in February 2019.

The charity set up in his name provides rapid access to mental health support in communities across Wales.

It already operates two hubs, at Ammanford and Swansea Football Clubs, to encourage people to come forward.

William met Janet and Jesse Lewis, the parents of Mr Lewis, for a private conversation by the pitch at the stadium.

They were joined by Rhys Fisher and Shaun Williams, former teammates of Mr Lewis at Ammanford FC.

The prince then spoke to Wales rugby captain Jac Morgan and head coach Steve Tandy.

William asked Mr Morgan and Mr Tandy about their experiences with mental health support as their careers progressed.

'I've heard from some football guys that when they reach a certain level, mental health becomes harder to talk about,' he said.

'Do you feel, as your career has progressed, that it gets harder to talk about it and be open about it?'

Mr Tandy said he aimed to create an environment for players to talk about mental health, regardless of level.

As he left the table, William said to Mr Tandy 'good luck, we need you' before telling Mr Morgan: 'We really need you too.'

More than 7,000 people die by suicide each year in the UK, equating to an average of 19 lives lost per day.

Men consistently account for 75 per cent of suicides, with rates the highest in the North of England and Wales, as well as deprived areas across the UK.

William was told that men are usually more reluctant to come forward and seek support, though the Jac Lewis Foundation hubs are now seeing an even amount of men and women. 

He spoke to two men who had benefited from the support of the charity and asked whether their radar for spotting when people in their lives might need support had improved.

'I think that's the bit we need to be better about in society, at reading each other,' William added.

He then joined a group of people who were painting stones, choosing a red paint for his pebble as he was in Wales.

He was approached by Bethan Mair, who handed William a pebble she had painted with a picture of a flower.

Ms Mair told William how her partner, Rhys, died by suicide in May last year and she received counselling through the Jac Lewis Foundation.

Describing William, she said: 'Everybody gives royals bunches of flowers so I thought I would paint a flower on a pebble as a permanent reminder of today.

'As a person who has also been through lots in his life, he was full of compassion and genuine empathy, I think.'

William placed his hand on Ms Mair's shoulder as she told him her experiences and thanked her for the pebble, adding: 'I will hold on to this'.

Callum Humphreys, mental health manager for the Jac Lewis Foundation, described the royal visit as 'amazing' for the charity.

'It's a once-in-a-lifetime experience,' Mr Humphreys said.

'It is great that he has come, it is great for the foundation and brings hope for everybody.'

The Jac Lewis Foundation, based in Ammanford, provides help with practical issues such as housing, finance, training and legal matters.

Its new hub at the Principality Stadiums is part of a partnership with the Welsh Rugby Union, supported by the Royal Foundation of the Prince and Princess of Wales.
