Detailed plans for restoring the UK Parliament’s sovereignty after Brexit are to be published within days, The Telegraph understands.

Proposals for converting EU law into UK law and repealing the legislation that took Britain into the bloc will be published when Brexit is triggered.

A small number of drafts of the White Paper, which is said to be around 50 page long, have been circling Whitehall in recent weeks.

Government sources said the document will be published when Theresa May formally triggers Article 50 by the end of this month. Whitehall figures believe the date will be March 29.

Proposals will reveal full details for how the Government will end the rule of European law by introducing legislation dubbed the “Great Repeal Bill”.
