DUP hoping to conclude deal with May as soon as possible

In another development, the traditionally moderate Unionist and Nationalist parties in Northern Ireland, the Ulster Unionist Party and the Social Democratic and Labour Party respectively, lost all their seats. The chances of the Brexit negotiations collapsing have also increased.

On Tuesday May, following a meeting with French President Emmanuel Macron in Paris, reiterated her government will get on with Brexit and make a success of it.

Leaders on both sides of the Irish Sea have expressed alarm that Brexit could lead to the restoration of a hard border between Ireland and Northern Ireland, with fears that such a move would affect the peace process.

Divisions over Europe helped sink the premierships of May's predecessors Margaret Thatcher, John Major and Cameron, and many of her lawmakers and party members favour a sharp break with the EU.

A majority of voters in Northern Ireland - 56 percent to 44 percent - elected to stay in the European Union in last year's referendum. As unionists, they'll want to strengthen the hand of the union and get money going into infrastructure and big capital projects.

Where does all this leave the DUP and can it exert influence?

May had promised to take Britain completely out of the bloc's common trading area and slash the number of people coming from the EU.

During that scandal, DUP First Minister Arlene Foster ignored repeated calls for her to step aside while an investigation is carried out into the scheme - which could cost taxpayers in the North in the region of £400 million (about €460 million), possibly more.

But back in Northern Ireland, there is a sense that hope for a continued peace is fading. The DUP is believed to want a comprehensive free trade and customs agreement with the European Union and arrangements to facilitate ease of movement of people, goods and services.

Rule over Northern Ireland is due to revert to London if parties fail to reach a deal on a power-sharing government, but what that means for the country if the DUP is a part of that government at Westminster remains to be seen.

"It's imperative that both governments recommit to the word, spirit and implementation of the Good Friday Agreement if there is to be any prospect of re-establishing the Executive".

Penned by the former deputy first minister at the time of his January resignation from Stormont, it mapped out obstacles to power-sharing in Northern Ireland.

In Dublin, Mrs Foster brushed aside Sinn Féin assertions that DUP support for the British Government compromises the 1998 Good Friday Agreement.

"We have just finished a meeting with the British prime minister and her secretary of state, and we told her very directly that she was in breach of the Good Friday agreement", said Mr Adams, speaking from Downing Street. Ironically, unionists a century ago at Westminster were in need of as hard an Irish Border as possible; now, the talk is of the DUP pushing for a "soft Border", but this is merely a slogan.

And some fear the viability of Northern Ireland's fragile peace - which has held since 1998 after decades of inter-community violence known as The Troubles - could rest on the arrangement, with doubts around the United Kingdom government's neutrality.
