Mark Coles profiles Dr Tedros Adhanom Ghebreyesus, who was the first African to be elected Director-General of the World Health Organisation. Three years on, he finds himself at the centre of a political storm. Some say he has been too soft on China - where the coronavirus began. Others accuse the WHO of being too slow to declare a global public health emergency and US President, Donald Trump, has threatened to withdraw funding. Now one of the most recognisable faces in the world due to the pandemic yet little is known about Dr Tedros Adhanom Ghebreyesus.
