The Duke and Duchess of Sussex are understood to be returning for an 'extended period', with Archie and Lilibet set to enrol at a British school.
But there will be no coming back into the royal fold, and the family is set to move into a non-royal residence.
Experts speculate the couple's return comes amid the ending of lucrative TV deals, financial constraints, PR mishaps and fractious relationships with Hollywood's elite, with some suggesting Meghan had 'burnt her bridges' in the US.
Archie, seven, and Lilibet, five, are thought to have already enrolled at a British school - and the family are reportedly planning to stay until the children finish their education.
The couple's latest move will bring them full circle back to the country they left in 2020. So just what have the couple been up to since they parted from royal life?
From London to California...and back again

Meghan announces she has had a miscarriage in an essay for The New York Times.
She wrote: 'After changing his [Archie's] diaper, I felt a sharp cramp. I dropped to the floor with him in my arms, humming a lullaby to keep us both calm, the cheerful tune a stark contrast to my sense that something was not right.
'I knew, as I clutched my firstborn child, that I was losing my second.'
Meghan and Harry strike a multi-year deal with Spotify through their company Archewell Audio, named after their son. Meghan's show Archetypes starts airing in 2022.
