Is the DUP ready to act? It depends on who you ask.

In the party of Arlene Foster there are, as in every other political party, different opinions.

There is the more pragmatic and more ideological wing.

Some of them reject the prospect of Brexit soon and the potential impact on business and agriculture.

But others are ready to take that risk, those who have spoken out on behalf of Nigel Farage for a holiday vote.

However, there is one thing that connects them, and the clue is in their title: They are a trade union party.

The DUP will never give in, if they believe it jeopardizes Northern Ireland's place in the UK.

There has been a change in tone – away from the rhetoric of "bin the backstop".

They reaffirm their readiness to accept greater cross-border alignment in the agri-food sector.

Arlene Foster insists that the backstop must be removed from the table

"It's very important that the backstop goes"

However, this is far less than the British or even the Northern Irish backstop.

Will the DUP accept that Northern Ireland remains in the EU Customs Union while the rest of the United Kingdom is leaving?

"Never, never, never …" to borrow the cult words of its founder, the late pastor, Ian Paisley.

But a Brexit without agreement is a double-edged sword for unionists – any tightening of the Northern Ireland border will only accelerate the demand for Irish unity.

There is another hurdle to the reported breakthrough – the DUP would almost certainly require Stormont to have a veto.

The decentralized government collapsed two and a half years ago and there is no sign that it will return soon.

Sinn Fein will not be in any hurry to help Irish Prime Minister Leo Varadkar and Arlene Foster in upcoming elections.

The DUP does not speak for the majority in Northern Ireland or exerts so much influence in Westminster.

Despite his votes, Boris Johnson can no longer get a majority in parliament.

There are reasons why it would want a solution, not least the deafening chorus of calls for a home.

But the constitutional question surpasses everything else and gives the ideological wing an advantage in every fight.

Even if the lady wanted to turn around, she would face a Herculean task if she turned her entire group around with her.
