Prince Harry pictured in southern Africa with Princess Senate Seeiso just hours after leaving London

"Had a pleasure of hosting a lunch today," she wrote in the picture, which was shared as a reel.

Princess Senate Mohato Seeiso, aged 23, is a princess of Lesotho.

She is the eldest child of King Letsie III of Lesotho and his wife Queen 'Masenate Mohato Seeiso.

The Duke of Sussex's appearance in southern Africa comes just hours after Harry attended the WellChild Awards in London on Monday.

The father-of-two has now spent more than a week away from Meghan Markle, Prince Archie and Princess Lilibet.

The duke has headed to southern Africa without seeing any of his family in the UK.

Harry travelled to the region for events in support of his charity Sentebale.

The royal will visit Lesotho for a gathering of business leaders, philanthropists and local stakeholders.

This will be aimed at driving forward the work of Harry's youth-focused charity, supporting the digital and economic inclusion of the next generation in Africa.

Prince Harry founded Sentebale, which means "forget me not", in 2006 to honour the late Princess of Wales.

Meghan did not join Harry on the trip, despite not having seen him 10 days.

The Duke of Sussex previously spent a week in New York with a series of engagements.

This included an event in honour of his mother Princess Diana.
