The March 2020 independent Windrush Lessons Learned Review[1][2] conducted by the inspector of constabulary concluded that the Home Office had shown "ignorance and thoughtlessness" and that what had happened had been "foreseeable and avoidable". It further found that immigration regulations were tightened "with complete disregard for the Windrush generation" and that officials had made "irrational" demands for multiple documents to establish residency rights.[3]
