Sam Coates ( sky news ) question? = ...

Sam Coates of Sky News asks how quickly people in the NHS can expect to get dexamethasone. He also asks why the drug has been put on the export ban list. "I'm not aware of that," says the PM, replying to his second question first. "It sound peculiar to me," he adds, and promises to look in to whether it is on the export ban list and if so why. On the first question, Patrick Vallance says the chief medical officer will issue guidance to say it should be used for medical practice shortly. He reiterates that the drug is inexpensive and widely available.
