Question to the Home Office:

To ask the Secretary of State for the Home Department, what data her Department has used to train AI systems used in immigration decision-making; and if she will publish that data.

In the areas of immigration, immigration intelligence and immigration enforcement, we do not use machine learning or other forms of artificial intelligence to make decisions on whether to grant or refuse leave, or to take immigration enforcement action.

Where such algorithmic tools are used within business processes, they will be typically trained on the data used in the business process itself.

To safeguard our operations, we do not routinely publish the data that is used and for external providers it will depend on their development processes.
