A Downing Street spokesperson said:
This afternoon Prime Minister Theresa May spoke to Taoiseach Enda Kenny following the recent elections in Northern Ireland.
They discussed their shared commitment to work with the parties to move forward and create a stable administration which ensures a strong, peaceful and prosperous Northern Ireland.
To that end, Secretary of State for Northern Ireland James Brokenshire and Irish Foreign Minister Charlie Flanagan will meet the parties on Wednesday and the Prime Minister and Taoiseach agreed to discuss the issue again at the EU Council on Thursday.
