Since its inception, the National Health Service has always relied on doctors and nurses who have been trained overseas. How does it plan for the workforce it requires? In the second of two programmes exploring today's health service, doctor-turned-journalist Smitha Mundasad, asks why the NHS is currently facing a recruitment crisis on so many fronts. She'll ask what impact Brexit could have. Can pharmacists, physician associates and other health workers do some of the work doctors do, and so reduce staff shortages? And will the NHS start training more of its own workforce? Presenter: Smitha Mundasad Producer: Rosamund Jones.
