Britain's Prince Harry and his wife Meghan, the Duke and Duchess of Sussex, are expecting their second child, a spokesperson for the couple said on Sunday.

Harry and Meghan stepped back from royal duties in January 2020 and moved with their first son Archie to Southern California to live a more independent life and escape the British media.

"We can confirm that Archie is going to be a big brother. The Duke and Duchess of Sussex are overjoyed to be expecting their second child", the spokesperson said.

Archie was born in 2019.
