Artistic swimmers promote Paris 2024 in London

STORY: The swimming quartet, which included former Team GB Olympians Asha Randall and Katie Clark, took the plunge at London's Covent Garden in a temporarily installed pool - complete with bar stools.

The event was to publicize the activities of On Location, the official hospitality partner for the Paris 2024 Olympics. It says the event is proving more popular than any other Games with their client base.

It also said it is working closely with Paris organizers to ensure the safety of those visiting, especially around the opening ceremony. That event is due to take place along the River Seine in the centre of the French capital and has prompted security concerns.
