Princess of Wales and Princess Charlotte are spotted riding the Elizabeth Line together in London

Kate Middleton and her daughter Princess Charlotte were filmed on the Elizabeth Line on Saturday, October 10, in footage that spread rapidly online. Passenger Aislinn Condra caught the pair on camera travelling from Slough station to Tottenham Court Road. Three security officials accompanied the royals, who paused to chat with fellow passengers sitting across from them on the journey.

The candid moment reinforces Kate's image as a hands-on, down-to-earth mother despite her royal status.

The sighting comes as OK! magazine dubs Kate the "saving grace" of the Royal Family in a new collector's edition dedicated to her rise.

The Princess of Wales is described as throwing herself into royal duties with 'fresh zest and renewed purpose' after the trials of recent years.
