Ireland is likely to gain two extra seats in the European Parliament as a result of Brexit.
At their informal summit in Brussels, leaders of the 27 remaining states are said to be broadly agreed on a series of changes to EU institutions that arise from Britain's departure.
Leaders are reported to be broadly in favour of a plan to reallocate 27 of Britains 73 seats in the European Parliament to 14 smaller states after Brexit.
They are also said to support each state keeping a member of the European Commission - something that they were required to review at this time.
In his intervention the Taoiseach also supported keeping the same system for choosing the president of the European Commission, which means the leader of the political group with the most seats in the European Parliament would get the job.
A French proposal for a transnational constituency, using the remaining British MEP seat allocation, is unlikely to be ready in time for next year's election because it would require a lot of changes to electoral laws.
Leaders have now moved onto discussing the EU budget
