Taoiseach Micheál Martin will address EU leaders on Friday on the impact of the UK's Internal Market Bill on the Brexit process, according to a senior EU official.
EU leaders meet in Brussels tomorrow for a two-day summit.
It will be dominated by foreign policy issues, such as the situation in Belarus, tension in the eastern Mediterranean between Turkey and Cyprus, and the poisoning of the Russian opposition leader Alexei Navalny.
European Commission President Ursula von der Leyen will briefly update EU leaders on progress in the future relationship negotiations with the UK.
A senior EU official has confirmed that the Taoiseach will be given the floor to outline his position on the Internal Market Bill, which seeks to override elements of the Northern Ireland Protocol.
"As Ireland is deeply impacted on this question of Brexit it is the intention of the President [of the European Council] to give him the floor," a senior EU said official.
The bill cleared its final House of Commons hurdle last night and will go to the House of Lords in Westminster.
British ministers argue the measures are necessary to provide a "legal safety net" to protect the Northern Ireland peace process if Britain fails to get an agreement on a post-Brexit free trade deal with the EU.
However, the UK government has faced fierce criticism from across the political spectrum for going back on commitments made in an international treaty.
