Statistics release cancelled

Due to a technical issue in the Second Generation Surveillance System (SGSS), data in SGSS has not correctly been updated since 5 March 2026. The cause has been identified and remediated but not in time for production of this week’s report, therefore the decision was taken to cancel this week’s report. This week’s figures will instead be included in next week’s report, which will be published on Thursday 19 March 2026
