Mother of epileptic boy says 'we're not out of the woods'

The mother of a 12-year-old boy with epilepsy has spoken to the media after he was rushed to Chelsea and Westminster Hospital on Friday night in a critical condition having suffered multiple seizures. Charlotte Caldwell had cannabis oil used to treat son Billy's condition seized at Heathrow Airport last week. However, Home Secretary Sajid Javid granted a 20-day emergency licence granting use of the oil after Billy was admitted to hospital on Friday night.
