UK will not agree anything that brings a hard Irish border

UK PM May spokesman has said that the UK will not agree anything that brings a hard Irish border.

A spokesman for UK PM May says the government will not agree anything that brings about a hard border on the island of Ireland.

Key statements:

• "Will not accept the UK being divided into two customs territories."
• "From time to time you'll read the Brexit optimists saying there is a 95% odd agreement between the UK and EU on a deal, the implication being that its pretty much a done deal." 

Also, The Times has cited a leaked letter from PM May that the European Union plans a customs border in the Irish Sea if there is not Brexit agreement.
