Question to the Home Office:
To ask Her Majesty's Government what discussions they have had with the government of the Republic of Ireland about allowing (1) Irish, and (2) UK citizens the freedom to (a) come and go between the UK and the Republic of Ireland, and (b) seek employment and establish residence in the UK, without special formalities, both before and after Brexit.
The Common Travel Area (CTA) arrangements allow British and Irish citizens to travel freely within the CTA without seeking permission from the authorities. They also provide for British citizens in Ireland and Irish citizens in the UK to be able to work in either country without any requirement to obtain permission from the authorities.
These arrangements pre-date membership of the EU. The UK and Ireland are working closely to protect these rights after the UK leaves the EU.
