Archie meets the Archbishop! Meghan Markle and Prince Harry take son to tea with veteran anti-apartheid campaigner Desmond Tutu 

Baby Archie today made his first appearance on the royal tour when he met one of the heroes of the anti-apartheid movement, Archbishop Desmond Tutu, the Daily Mail reports.

The four-month-old posed with the man they call 'The Arch' with his proud mother and father, the Duke and Duchess of Sussex, the Daily Mail reports.

The Sussexes this morning released adorable footage of them carrying their four-month-old, with the caption, 'Arch meets Archie!'. 

Video posted to their Instagram account shows the couple beaming as Meghan holds little Archie - who giggles at his mother - as they are greeted by Archbishop Tutu and his daughter, Thandeka Tutu-Gxashe. 

Prince Harry, 35, put a loving arm around his wife as they stroll along with Archie who stole the show, dressed for the occasion in baby blue striped dungarees and matching booties.   

Meghan, 38, joked with the Archbishop's daughter Thandeka Tutu Gxashe that the little royal would have to get used the cameras in his life, while Ms Tutu Gxashe joked little Archie was 'going to be a ladies' man'. 

The veteran Nobel Peace Prize-winning anti-apartheid campaigner - who effectively became the leader of the liberation struggle during Nelson Mandela's long imprisonment - said he was “thrilled by the 'rare privilege and honour” to meet the royals.
