Health secretary Matt Hancock announced last week that Public Health England will be replaced with a new National Institute for Health Protection. Baroness Dido Harding, who ran NHS Test and Trace in England, will be heading up this new agency too, for now. Who is she?

Dido Harding started out on a pig farm in Dorset, and has spent most of her adult life splitting her time between the corporate world and her beloved horses.
