The NHS is the world’s fifth-largest employer, behind the US department of defence (3.2m), Chinese People’s Liberation Army (2.3m), Walmart (2.3m), and McDonald's (1.9m).
There are 37 NHS trusts with more than 10% of their workforce from the EU. Top of the list is Royal Brompton and Harefield, and Oxford University Hospitals, with 19%.
