Britain has published a draft bill that would formally put an end to its membership of the European Union and end the supremacy of EU law.
The first line of the bill said the legislative cornerstone of Britain's membership, the European Communities Act 1972, would be "repealed on exit day".
Labour has said it will vote against the major legislation unless it contains a provision to put the European Charter of Fundamental Rights into British law, but the bill confirms it will be ditched.
It is the first of many fierce battlegrounds on the legislation, formally titled the European Union (Withdrawal) Bill.
Liberal Democrat leader Tim Farron has warned ministers they face "hell" as they to get the bill, a central plank of the government's Brexit strategy, through the Houses of Commons and Lords.
