Ainsley Harriott has said his sister is "doing fine" after she tripped and fell into a water feature at the Chelsea Flower Show.
Paramedics were called after the TV chef's sister Jacqueline, a retired teacher, was injured in the fall at the BBC show garden at the event.
Harriott, 65, tweeted: "Just a big thank you to everyone who helped my sister when she had a fall at the Chelsea Flower Show this morning. She’s doing fine and all is well."

Pictures showed Jacqueline being helped out of the water and put into the recovery position.
She had been Harriott's guest at the VIP event and was among those admiring the Our Green Planet and RHS Bee Garden exhibit when she stepped backwards and fell into the pond, with witnesses saying she was completely submerged and ingested a considerable amount of water.
A Chelsea Flower Show spokesman told MailOnline: "We are investigating an incident that occurred on a garden at RHS Chelsea Flower Show today.
"The guest was quickly attended to by on site medical professionals and we are pleased to say is now home and well."
Other guests at the party included DIY SOS star Nick Knowles.
Jacqueline worked for 39 years as a teacher before her retirement. She is now a committee member for the Croydon branch of U3A - an international movement offering education and cultural stimulation to retired members of the community.
She and Ainsley and their brother Chester are the children of Jamaican-born pianist and singer, Chester Leroy Harriott.
Harriott - who is currently presenting Best Of Britain By The Sea with Grace Dent on Channel 4 - has previously admitted his sister is critical of his cooking.
He told The Guardian in 2021: "My sister, when she comes over, will say, 'I saw your programme the other day and you did okay.' But that’s it for the praise. I take it on the chin. She’ll stir things I’m cooking at home and take control."
Harriott rose to fame in the 90s on BBC breakfast show Good Morning with Anne and Nick.
