To ask His Majesty's Government what deficiency in NHS England’s Secure Data Environment was described in paragraph 5.1.10 of the minutes from the 29 February meeting of the Advisory Group for Data, and what steps are being taken to rectify that deficiency.

The point made in the meeting was unrelated to any deficiency within the Secure Data Environment (SDE). The requirement from the Home Office is for specific statistical models and systems to be applied across the dataset requested, which is made up of aggregated data. This specific functionality is available from within the Home Office’s own technical environment, and not from within the SDE. There are no plans at this time to migrate this functionality within the SDE.
