Seems like May is competing with McConnell for the biggest car crash:

DUP: Government talks ‘have not proceeded in a way we would have expected’

[…]

It is thought that the DUP is asking for more investment for Northern Ireland as part of the price of its support, and the party also wants the retention of the triple lock guarantee on pensions and winter fuel allowances for older people.

Arlene Foster’s party backs Brexit, but wants to avoid any disruption to movements across the border with the Irish Republic.

[…]

How that can work is really a mystery. Ireland is part of the EU and will follow EU laws/rules for movements across boarders.
