The goal of this clinical feasibility trial is to learn whether the investigators can improve sleep and reduce sedentary behaviour in people living with Type 2 diabetes mellitus with sleep problems. The main questions it aims to answer are: • question 1, can objectively measured sleep and sedentary behaviour be improved in the participants and • question 2, what effect will this have on a number of physical and physiological markers. Participants in the intervention group will be asked to keep sleep diaries and attend regular meetings with a qualified coach who will use a specific talking therapy to try to improve sleep and with use behaviour change techniques to help them be less sedentary. Researchers will compare the control group to the intervention group to see if effects differ between groups.

Data in anonymised form may be suitable for sharing at the end of the trial. Should there be concerns about protecting the identity of participants/commercialisation of outputs, access restrictions will need to be considered. If suitable, anonymised data may be added to UoL's Research Archive (https://figshare.le.ac.uk/) within 6 months of the trial end date. The repository is registered in OpenDOAR and preserves research outputs (minimum of 10 years).

The technicians analysing the accelerometer data and blood analysis will be blinded as to which arm the participant is from, no other masking is possible.
| Control - usual care | Other | Participants will be given a leaflet summarising good sleep practice and the advantages of reducing sedentary behaviour. Participants will complete a number of questionnaires and tests at baseline and at completion to allow comparisons to be made. |
|
| Sedentary behaviour reduction | Behavioral | Participants will be encouraged to increase activity and thus reduce sedentary time. Investigators will use behaviour change techniques to aid in this goal. Participants will complete a number of questionnaires and tests at baseline and at completion to allow comparisons to be made. |

| Subjectively measured sleep - insomnia | The Insomnia Severity index, will be used to measure the level of insomnia - it is a questionnaire and has a range of 0-28 with higher scores indicating more insomnia. | Before and after the 12 week intervention/intervention period |
| Subjectively measured sleep quality - | The Pittsburgh Sleep Quality Index will be used to measure subjective sleep quality, this is a questionnaire and has a range of 0-21 with higher scores indicating worse sleep quality. | Before and after the 12 week intervention/intervention period |
