The Windrush scandal began to surface in 2017 after it emerged that hundreds of Commonwealth citizens, many of whom were from the “Windrush” generation, had been wrongly detained, deported and denied legal rights. [...] As these shocking stories hit the headlines, Caribbean leaders took the issue up with then-prime minister, Theresa May. [...] Commonwealth citizens were affected by the government's “Hostile Environment” legislation – a policy announced in 2012 which tasked the NHS, landlords, banks, employers and many others with enforcing immigration controls.
[...] Because many of the Windrush generation arrived as children on their parents' passports, and the Home Office destroyed thousands of landing cards and other records, many lacked the documentation to prove their right to remain in the UK. [...] Falsely deemed as “illegal immigrants”/“undocumented migrants” they began to lose their access to housing, healthcare, bank accounts and driving licenses. Many were placed in immigration detention, prevented from travelling abroad and threatened with forcible removal, while others were deported to countries they hadn't seen since they were children.
Their harmful and unjust treatment provoked widespread condemnation of government's failings on the matter, with calls being made for radical reform of the Home Office and the UK's immigration policy. In response to these demands, then Home Secretary, Sajid Javid announced in May 2018 that the Home Office would commission a “Windrush Lessons Learned Review”.
