The royals were greeted by pipe playing musicians and cheering crowds as they walked down the red carpet which had been rolled-out for their arrival, with Meghan mobbed by young fans.

The Duchess later gave a speech to university students, the first words she has spoken during their 16-day Commonwealth tour, which is more than half-way through.

Meghan spoke of how the "journey of higher education is an incredible, impactful and pivotal one".

"I am also fully aware of the challenges of being able to afford this level of schooling for many people around the world – myself included. It was through scholarships, financial aid programmes and work-study where my earnings from a job on campus went directly towards my tuition - that I was able to attend university," she said.

"And, without question, it was worth every effort. Everyone should be afforded the opportunity to receive the education they want, but more importantly the education they have the right to receive. And for women and girls in developing countries, this is vital.

"Providing them with access to education is the key to economic and social development. Because when girls are given the right tools to succeed, they can create incredible futures, not only for themselves but also for those around them."

Inside the university, the couple observed a cultural performance on the effects of climate change in the Pacific from the university's Oceania Dance Troupe, before meeting students studying subjects from agriculture to women's development.

Their Royal Highnesses were hosted by Queen's Young Leader Elisha Azeemah Bano and Commonwealth Youth Award winner Elvis Kumar, both of whom are USP students.

The event was live streamed to a number of the university's campuses throughout the Pacific region.

Harry also made a speech in his capacity as Commonwealth Youth Ambassador.

The couple then went in separate directions.

The Duke travelled to Colo-i-Suva Forest Park and The Duchess to the British High Commissioner's Residence, before heading to Suva Market.

The Duke of Sussex had earlier left a touching handwritten note in Fijian at a wreath laying ceremony at the national war memorial in the Pacific Island nation.

He was up early to lay a poppy wreath on Wednesday, which carried the personal message "In grateful memory of those who made the ultimate sacrifice in the service of their country. Loloma kei na masu. Harry".

The wording in Fijian means love and prayers.

He also meet with a number of Fijian war veterans, some of whom served with the British Armed Forces, on his second day in the country.

Pregnant Meghan stayed behind at their luxury Suva hotel as her husband attended to his early morning official duties.
