Launched in 2003, Desmond was designed to teach people who already have type 2 diabetes the skills necessary to live with the condition.

The research, led by the Leicester Diabetes Centre, showed that in over 1,670 people with diabetes who completed the course between 2014 and 2015 they had reduced HbA1c levels of about 1 per cent.
