Prince Harry and Meghan 'turned back the clock' with 'an homage to their Royal days' a new video message released today, a body language expert has said.

The Duke and Duchess of Sussex made their first joint appearance in nearly three months today as they spoke about online violence against children - a cause that is deeply important to them.

Both wearing dark blazers with Remembrance poppies fastened on their lapels, the Sussexes called for greater protections for 'the most vulnerable in our world' against the threat of digital violence and harm.

Analysing the video, body language expert Judi James told MailOnline: 'The couple's appearance and body language make it look as though they have turned back the clock to the times when they appeared as a royal couple at the Remembrance service in the UK.'

Ms James said that it felt like when 'Harry was very much the alpha prince and Meghan was taking her lead from him as she learned the ropes'.

She added: 'Meghan looks less assertive here and she appears to be copying and mirroring her husband, taking her cues from him. 

'Although she starts with her hands clasped in front of her body, by the end of the video she has repositioned to copy Harry's pose with her hands clasped behind her back. 

'She is the one throwing the frequent glances at her husband as he speaks, smiling warmly and fondly in a gesture of encouragement and support. 

'This constant gesture makes her appear like the more openly loving one in the relationship while Harry seems intent on staying in role and projecting formality. Her entire delivery is confident but softer and more loving as she speaks to camera.

'There is one point though where he seems to want to re-define their unity as a couple and a professional double-act. Recently we've seen them separate to pursue individual causes or careers but this video seems to stress that the intrinsic relationship bonds are still intact.'

After their two-minute speech, they couple a sweet moment as Harry, 40, affectionately wrapped his arm around Meghan, 43.

Discussing this tactile moment, Ms James said: 'At the sound of the word 'together' Harry appears to take his cue quickly, extending one arm so his hand is behind his wife's back.

'This is a subtle PDA from a couple who have previously flirted, touched and even kissed each other on screen. But their cause here is a serious and important one so this slightly self-conscious-looking, more formal PDA seems to be more appropriate.

The video message was played at the inaugural Global Ministerial Conference on Violence Against Children in Colombia, as the Duke and Duchess called for greater protections for 'the most vulnerable in our world' against the threat of digital violence and harm. 

Ms James commented that although their words define their campaign against violence against children, 'Harry and Meghan's visual image looks very much like a royal homage to Remembrance day.'

She added: 'Their side-by-side poses straight to the camera look regally formal and official. They wear matching, tailored navy jackets that make a feature of the poppies in their lapels. 

'Harry is emphatically in royal military mode, standing unsmiling, with his hands behind his back and rising up onto the balls of his feet and dropping down again as though briefing the troops.

'His tone is serious, authoritative, concerned and assertive. He barely glances at Meghan and the first time he does his facial expression looks severe although it softens during the second glance.'

The Sussexes' last official appearance together was in August, when Harry and Meghan embarked on a four-day tour of South America.

The new video message appears to have been filmed in California, where the Sussexes reside with their children, Archie and Lilibet. 

Harry opened their address at the inaugural ministerial conference on 'ending violence against children' by saying: 'We are at a crossroads where the urgency to reassess and redefine our approach to protecting children has become increasingly evident. 

'While the necessity has always been apparent, it is now time to translate that awareness into meaningful action.'

Meghan added that while 'greater connectivity and advanced technology' have obvious advantages, they also 'compel us to better understand how digital violence against children is manifesting itself' in 2024. 

She continued: 'At the Archewell Foundation, we engage with young people, families, and experts worldwide learning how every aspect of a child's life - from their livelihood to their physical and mental wellbeing - now operate within an online economy that has the power to both shape, and misshape, our connections.' 

Harry and Meghan launched the Parents' Network, an online campaign aimed at tackling harm caused to children online, in August this year.  

Their initiative aims to help offer a 'safe and supportive community [which] is available to all caregivers navigating the complex digital world'. 

According to the Sussexes' Archewell Foundation website, this group includes those who 'have first-hand knowledge of the pain and destruction caused by social media use'.

Speaking about the Parents' Network on Thursday, November 7, Harry described it as a 'support network for families dealing with online harm'. 

He continued: 'Through trauma-informed practices, we help parents come together to forge strong bonds, offering healing support through community with the ultimate goal of prioritizing safety at the source.'

Meghan added that while it's important for parents to 'establish norms around the use of and access to technology', it's imperative to formulating standards and regulations that 'prioritise children's safety'. 

Prince Harry ended their message with an urgent call-to-action: 'Young people are calling for help. Families are desperately seeking support. 

'They are urging us to leverage the resources in this room to confront the new reality our youth are facing.

'We look forward to the actions and outcomes of the discussions that will take place here in Colombia, and are grateful for the leadership, expertise, and testimonies that will come together in this room to address all forms of violence targeting the most vulnerable in our world.' 

Meghan added: 'Together we can harness this moment to drive lasting change.' 

Harry and Meghan gave their first broadcast interview together in three years this August, when they sat down with CBS News host Jane Pauley to discuss the Parents' Network initiative. 

During the interview, the couple said they want to 'be a part of change for good' when it comes to the 'online space'. 

The campaign, which carries the slogan #NoChildLostToSocialMedia, includes a video which has been posted on the Foundation's website and features parents who have lost their children to suicide because of online harm. 

In addition, a list of three guides has been posted on the site, each tackling a social media platform, including Instagram, Snapchat, and TikTok.

The guides are described by the site as being 'repurposed in partnership with The Social Media Victims Law Center'.

Compiled using information from the Center's online social media guides, they include information about what each platform is used for, and how caregivers can 'improve their child's safety' while they are using them.

Earlier this year, Harry and Meghan released a clip urging social media companies to restrict the amount of harmful content children see online. 

On 31 January, they released the video of their appearance at a World Mental Health Day discussion in New York in October last year. 

They issued the video on their Archewell website following a US Senate Judiciary Committee hearing on online child safety which took place in Washington yesterday - and saw politicians warn social media giants: 'You have blood on your hands'.

In the video - released with a statement on online child safety - Meghan said: 'When the car was first invented, there wasn't a seatbelt. And what happened? People started to get hurt, people started to die. So you started to change the car.'

Harry says: 'We need to get out of this idea that young kids, there's something wrong with them. No, it's the world that we're allowing to be created around them. Please stop sending children content that you wouldn't want your own children to see.' 

The video dates back to October 10 last year when the Sussexes urged social media companies to reduce the amount of harmful content children see online to protect their mental health.

Harry and Meghan made the remarks at a mental health awareness festival run by non-profit Project Healthy Minds in New York.

The royal couple, who have spoken about their own mental health issues, took part in a panel discussion alongside US surgeon general Vivek Murthy moderated by NBC host Carson Daly, who has spoken of his struggles with anxiety.

The event, on World Mental Health Day 2023, was co-ordinated by the Archewell Foundation.

The couple called on social media firms to adopt better content moderation policies and tweak apps which can prove addictive for youngsters.

They spoke after hearing from parents who have lost children to mental health issues linked to social media use.

The Duke urged tech bosses to 'stop sending children content you wouldn't want your own children to see'.

The Duchess said she and her husband are focusing on what they can do behind the scenes to make social media use 'safer, better and more positive' and that the couple have spoken to tech executives about the issue.

She added: 'People are getting hurt – and people, specifically children, are dying.

'A year ago we met some of the families, not all of them. At that time, it was impossible to not be in tears as I'm sure so many of you have been today hearing these stories.

'As parents, our kids are really young – they're two-and-a-half and four-and-a-half – but social media is not going away.

'I think by design, there is an entry point that is supposed to be positive, in creating community and something has devolved, and there is no way to hear that and not try to help these families have their stories be heard.'
