The Telegraph reported the UK's Prime Minister Theresa May will seek a Brexit breakthrough when she meets with the DUP on Wednesday after saying the backstop would not be removed from her Withdrawal Agreement.

According to the report, May's meeting with Arlene Foster, the DUP leader, will be closely scrutinized given the PM is reliant on the party’s 10 MPs to command a majority in the House of Commons.

Ms. Foster has said her party would support Mrs. May’s deal if the backstop issue can be resolved but is yet to say exactly which solution to the problem she would favor.

The meeting of the pair will come as Leo Varadkar, the Irish Taoiseach, visits Brussels for meetings with Jean-Claude Juncker, the European Commission president, and Donald Tusk, the European Council president.

Mr. Varadkar is expected to seek guarantees of support from the EU to mitigate the impact of a potential no-deal Brexit on Ireland.
