Inside a clinic taking on childhood obesity

With thousands of children across England starting primary school for the first time, we look at the network of specialist NHS weight-loss centres tackling childhood obesity. The World Tonight’s Alice Aylett Roberts gained exclusive access to a clinic, where she meets parents, medical pracitioners and a six-year-old patient. Also on the programme: imprisoned Hong Kong activist Joshua Wong pleads guilty to new charges that could see him face life behind bars; and the King and Queen, alongside French President Emmanuel Macron and his wife Brigitte, visit the Bayeux Tapestry ahead of its unprecedented opening at the British Museum next week.
