The University of Leicester is opening its new medical teaching and research building this evening.
It will be opened by Sir David Attenborough and his brother Michael, and will be named after the founder of the Leicester-based retailer 'Next', George Davies.
It comes after he made a donation of £5.15million towards research into vascular disease, and to create the Vascular Limb Salvage Clinic at Glenfield Hospital.
Sir David and Michael Attenborough are co-patrons of the University of Leicester's Centenary, which the University will commemorate from 2018 to 2021.
University bosses say the George Davies Centre will transform medical teaching and improve the lives of many patients.
The £42million building will house the University's Medical School, School of Psychology and Department of Health Sciences.
