I was fortunate to work with Margaret on and off for many years. She was a stalwart of the DfT Analyst Community who took pride in her work, her team and the stats and social research professions. She was a force to be reckoned with – never afraid to share her opinion or to challenge when necessary, and to defend her work and that of her her team. Most importantly she always did so in a constructive and collegiate way. She worked hard, but always made time for a chat and to help others and never complained. Her boots will be very tough to fill, but more than that Margaret will be very much missed by all in the department who knew her and I am very grateful to have had the chance to work with her.
