The draft Home Office document published by the Guardian today reveals plans to make it much harder for low-skilled EU workers to settle in Britain.
It would also make it harder for EU workers in Britain to bring in family members to join them.
The 82-page document does not represent official policy and has not been approved by ministers. It has been circulated among senior government officials.
It suggests the new restrictions would come into force as soon as Britain formally leaves the European Union.
