After a tumultuous day which saw a choreographed attempt to showcase the progress of Brexit talks thwarted at the last minute, May will try to gauge on Tuesday what her supporters in Northern Ireland's Democratic Unionist Party (DUP) might accept.
Commission European President Jean-Claude Juncker gave a speech at just before 7am saying sufficient progress has been made to move onto the second stage of the terms of the divorce.

Scotland's nationalist leader showed little patience, accusing the British government of being "totally and utterly incompetent" on Brexit. "The sooner we are in control over our own future here in Scotland the better, and this week has proved it", she added. Dijsselbloem, the Netherlands finance minister who chairs meetings of his counterparts in the 19-country eurozone, said that some businesses would nevertheless have to relocate. "We've seen a rally in the pound over the last couple of weeks on the expectation of a deal being agreed so what we may be seeing is simply a case of buying the rumour and selling the fact", he said.
