An open-label, multi-centre, randomized, two-arm parallel group trial comparing automated closed-loop and standard insulin delivery.~124 pregnant women between 18 and 45 years of age with Type 1 Diabetes of at least 12 months' duration on standard insulin delivery (CSII or MDI) will be recruited through outpatient antenatal diabetes clinics. Women fulfilling the eligibility criteria will be randomized to automated insulin delivery (AiD) or to continue standard patient-directed insulin delivery (CSII or MDI) without AiD. The study will take place within the home and NHS antenatal clinical settings.~Additional blood samples for the research will be obtained at the 24th and 34th week of pregnancy and questionnaires will also be completed by the participant at the 34th week of pregnancy. Following this we will collect information on the birth.~25 of the woman randomised to the closed loop insulin delivery system will also be interviewed to gain more information on, among other things, their existing diabetes management practices, everyday work and family lives and their experience with the device.
