Ireland is currently served by a Luxembourg embassy in London, with only a consulate based in Dublin.

Responding to a parliamentary question from CSV leader Claude Wiseler, Asselborn said that the Luxembourg diplomatic network would be reviewed at the start of the new government’s legislature.

“While it is unusual to diplomatically serve a European Union member state from a non-member state, there is no objective factor that would change this,” he wrote on 12 November. “It is not an urgent question to settle.”

Asselborn alluded to possible solutions in the reorganisation of diplomatic resources, which would include maintaining the status quo, serving Ireland from another member state, having an ambassador in Luxembourg or in Dublin.

“As for all decisions related to other diplomatic accreditations, several criteria will be taken into consideration, such as political assessment, cost and the effectiveness of diplomatic action.”

Asselborn’s response came before the publication of the draft withdrawal agreement between the EU and UK. In the event no agreement is reached on EU-UK relations, it outlines the establishment of a backstop in which Northern Ireland would be under different regulations in many areas to the rest of the UK to avoid a hard border between Northern Ireland and the Republic of Ireland.
