Question to the Home Office:

To ask the Secretary of State for the Home Department, what the immigration status of EU27 nationals resident in the UK will be in the event that the UK leaves the EU if they were given indefinite leave to remain by the UK Government before either (a) the UK joined the EEC or (b) their country of origin joined the EEC/EC/EU.

EU citizens who already hold indefinite leave to remain, regardless of when this was granted, can continue to rely on this status once the UK has left the European Union. They do not need to apply for status under the EU Settlement Scheme, but they may do so if they wish as, in line with the draft Withdrawal Agreement with the EU reached on 17 October 2019.
