The way I read it , it could be a way for Brits to remain EU citizens even after Brexit . And thereby avoiding HIC’s nightmare of cues at airports .

But for an EU rule that has been around since 2012 , I think they have left it late to start taking action .
“European Citizens’ Initiatives were introduced with the Lisbon Treaty and launched as an agenda-setting tool in the hands of citizens in April 2012, upon the entry into force of the European Citizens’ Initiative Regulation which implements the Treaty provisions.
Once formally registered, a European Citizens’ Initiative allows one million citizens from at least one quarter of EU Member States to invite the European Commission to propose a legal act in areas where the Commission has the power to do so. “
The European Commission registered a Citizens’ Initiative on Wednesday (18 July) that could end up securing EU citizenship for UK citizens once Britain leaves the EU.
“As Exit Day approaches on 29 March 2019, so does the prospect of millions of UK nationals losing their citizenship of the European Union. This will have a direct impact on people’s lives,” reads the website of the initiative.
“Millions of EU nationals residing, working and studying in the UK also live in limbo, anxiously awaiting the outcome of protracted negotiations which look set to downgrade their rights.”
The Permanent EU citizenship initiative is the latest example of the participatory democracy instrument that allows citizens to suggest legal changes in any field where the Commission has power to propose legislation. It was introduced in the Lisbon Treaty.
