The SDLP have called on the UK and Irish government's to write into law the Common Travel Area (CTA), to protect the agreement in both countries.

Currently the CTA is an inter-governmental agreement, but not part of internal UK law.

The Executive Office Committee chair Sinead McLaughlin said: "The British government can no longer be trusted when it comes to international agreements – we have seen that most clearly with its disregard for its commitments under the Northern Ireland Protocol. It has walked away from the very commitments it entered into with its eyes wide open.

"We are now seeing in the Borders and Nationality Bill serious threats to the rights of people born here and to those who have obtained Settled Status, who were told they could continue to live here. Yet the Bill proposes that the Government will be able to bar a person from the UK if they have a right to another nationality. That would potentially apply to the vast majority of people born in the North of Ireland.

"Given these uncertainties, it makes sense for the British government in particular, but also the Irish government, to put the Common Travel Area into their internal legislation. As chair of the Assembly’s The Executive Office committee I have written to the two governments requesting this, with the support of the committee at its last meeting in December."
