The leader of Northern Ireland's Democratic Unionist Party (DUP) which props up Prime Minister Theresa May's government said she would look at any new offer to the European Union (EU) on the Irish border, but Northern Ireland (NI) must leave on the same terms as the rest of Britain.

Earlier, British Prime Minister Theresa May said she is preparing to make a new offer regarding the border that is aimed at breaking the deadlock in the Brexit negotiations.

"We should wait to see what the text actually says in relation to any offer that has been made to the European Union," Arlene Foster, the leader of the DUP told Bloomberg Television on Tuesday.

"We always said that we have just the one red line - we cannot be separated from the rest of the United Kingdom, from a constitutional position and also from an economic reason as well."

In the meantime, Former junior Brexit minister Steve Baker said a plan by Eurosceptic rebels in Britain's ruling party to rely on technology to check goods on the north-south land border on the island of Ireland would resolve the stalemate.

"We believe that we have produced a proposal which can operate within the current framework of technology and administration to deliver a free flowing border with no infrastructure on the island of Ireland within the boundaries of a free trade agreement," Baker told BBC radio.

The question of an Irish border is one of the principal issues holding up a deal between Britain and the EU over Brexit, with less than six months to go before Britain leaves the bloc.

The issue has been hotly debated at the ongoing Conservative Party annual conference in Birmingham this week.
