The NHS needs Simon Stevens to stay

This morning, Boris Johnson should be calling Simon Stevens, his old Oxford Union rival, and urging him to stay on as head of the NHS for another year. The decision on the new head of the NHS is one of the most consequential decisions that Sajid Javid will make as Health Secretary and asking a newcomer to the brief to make this decision straightaway is unwise, especially as there is such a divide in opinion about who the best candidate for the job is.
