Great Britain wants to end the post-Brexit controls between Northern Ireland and the rest of the United Kingdom. The decision is considered the basis for the end of the political crisis in Northern Ireland.

The main Protestant party, the Democratic Unionist Party (DUP), had made an end to internal British customs controls a condition. The DUP advocates political union with Great Britain and now wants to return to the regional government in Belfast after two years of boycott. The contractually agreed regulation stipulates that the DUP must govern together with the strongest Catholic force, Sinn Féin, which seeks unification with Ireland.
