The DUP has warned Theresa May to "keep her side of the bargain" on Brexit after the party's 10 MPs withheld their support in votes on Budget measures.

Mrs May insists her draft EU withdrawal deal, which MPs will vote on next month, is the right one.

She remains under pressure from Tory MPs to seek concessions from the EU.

The DUP, which props up the government, said it was sending the PM a "message" over her plan to "separate" Northern Ireland from the rest of the UK.

The party's decision to abstain on a series of amendments to the Finance Bill on Monday night - as well as support an amendment proposed by Labour - was seen as a gesture, rather than an attempt to influence policy.

Mrs May's new-look cabinet meets on Tuesday for the first time since two ministers resigned last week, after they said they could not support the deal.

But the prime minister continues to be the target of backbench critics within her party, who appear intent on forcing a confidence vote on her leadership.

Something very worrying, however, for Number 10 has just happened for real; more important in this moment than the potential threat from their own backbenches.

The DUP, crucial to Theresa May holding on to power, has just abstained in votes on the finance bill. In other words, they decided not to back the prime minister on the Budget.

Why? We know that the DUP is furious about the compromises that Number 10 has made to get their draft deal with the EU.

And they want to show, loudly and clearly, that they are not on board.

A senior DUP source has just told me tonight's votes were deliberately designed to "send a message to Theresa May that if she wants to continue down the road of the withdrawal agreement and its effect on the Union then there will be repercussions in the Commons".

"She could be leading them to a very bad place," they continued. "Tory MPs need to realise that their jobs, their majorities, their careers depend on a good working relationship with the DUP and May doesn't appear to be listening."

Ouch. The DUP says this is not the end of the arrangement of the so-called "confidence and supply" agreement, where the government can formally rely on support from the Northern Irish unionists' 10 votes.

But the fabric of that arrangement is certainly torn... And once faith is broken between the two, it's hard to see it could be restored.

A senior DUP source said tonight’s abstentions in the Commons were designed to warn the government that "it can’t be business as usual".

They said the DUP was "sending a message to Theresa May that if she wants to continue down the road of the withdrawal agreement and its effect on the Union then there will be repercussions in the Commons. She could be leading them to a very bad place".

The source continued: "Tory MPs need to realise that their jobs, their majorities, their careers depend on a good working relationship with the DUP and May doesn’t appear to be listening."

The DUP have previously only abstained on one bill.

The source stressed, however, this was not the end of the confidence and supply agreement between the Conservatives and the DUP.

The breaking story in Westminster this evening if that the Democratic Unionists have declined to support Theresa May in a series of votes on the Finance Bill - legislation needed to enact measures in last month's Budget.

The DUP, on whom the PM relies for her Commons majority, even voted with Labour on one vote on child poverty.

Although the government did not lose any of Monday's votes, the development is highly significant given the DUP's support will be important when the PM tries to get the draft Brexit agreement through Parliament.

The DUP's confidence and supply agreement with the Conservatives also hinges on them supporting the government in Budget and Brexit votes.

As our Northern Ireland political reporter said earlier, it seems the DUP is sending a "shot across the bows" of the PM.

The draft Brexit withdrawal agreement stands at 585 pages long.

It sets out how the UK leaves the European Union, scheduled for 29 March 2019. Chris Morris, from BBC Reality Check, has been going through it in detail.

Jeremy Corbyn said "deep-seated change is needed to avoid a damaging Brexit that will hurt enterprise, jobs and living standards, and instead use it as a catalyst for economic transformation".

Tory MP Andrew Mitchell has expressed concerns about the withdrawal agreement, but would not go as far to say he would vote against it.

"There are some very serious difficulties with it," he told BBC News.

"The principal difficulty is we will leave the European Union as a rule taker," he added, meaning neither side would be happy.

And he said it was a "endless recipe for future discord and unhappiness."

Mr Mitchell said it might be that it becomes "right to let it through" Parliament and he admired the PM's "tenacity" on pushing for it.

But he concluded that, from his first reading, he had his issues.

The leader of the Democratic Unionist Party, Arlene Foster, has called the draft withdrawal agreement a "false choice".

Responding to remarks by the Irish Taosieach Leo Varadkar, Ms Foster said: "The Taoiseach's comments that the Irish government is not contemplating a hard border in the event the withdrawal agreement is rejected by Parliament underlines why a focus on the backstop was only ever a negotiating tactic by the European Union.

"We have been told that the backstop is only necessary to prevent such a hard border, but these comments make it clear that the EU's insistence on a backstop was not aimed at this.

"The European Union's focus on the border between Northern Ireland and the Republic has only ever been a negotiating tactic to secure its own aims in the negotiations.

"The comments also further underscore how the inclusion of a border down the Irish Sea within the current withdrawal agreement is not only unacceptable, but is also unnecessary."

She added: "The withdrawal agreement was based on the false choice that an internal UK border was the only way to prevent a hard border between Northern Ireland and the Republic."

Mr Varadkar said on Sunday he was not contemplating a hard border.

But on Friday he said one would be "very difficult to avoid" in the case of no-deal.

“It could not be clearer, business as usual is not working,” Mr Corbyn told the conference.

“And when the rules of the game aren’t working for the overwhelming majority, the rules of the game need to change.”

He called for a “new settlement for business and a stronger say for the workforce”, coupled with a government investing faster into infrastructure, education, skills and the technology.

Mr Corbyn said a “good Brexit plan” will involve more than negotiating with Brussels – it will need to include a “radical programme of investment and real change”.

He listed how the CBI and his party had agreed on a number of ways forward for the right Brexit.

And he said that Mrs May should be brave enough to follow their recommendations or stand aside for Labour to do it.

He added that people voted to leave the EU “against the economic backdrop of post-crash Britain”, where wealth was failing to trickle down and a million families were using food banks.

He said many voted in an "act of protest" at this.

Mr Corbyn called the deal a "blindfold Brexit" designed to get the country through this stage of the process "without seeing" where it will end up.

He said Theresa May's deal was "botched" and "half-baked" and said some were nervous about going against it, in case of a no-deal scenario.

But he said it was a "false choice" between Mrs May's deal and no deal, which was designed to scare people into backing the PM.
