SAJID Javid's allies furiously accused No10 of mining it from day one in order to force it to spend billions more.
As the fallout from the former chancellor's dramatic resignation worsened on Thursday, it turned out that the bitter spending feud was at the heart of Mr. Javid's exit from cabinet.

The Sun may also reveal that tensions between No10 and No11 have skyrocketed in the past two weeks, ahead of next month's budget.
Treasury officials have repeatedly rejected requests from Boris' team to turn on spending taps and respect the Prime Minister's three main electoral wishes - leveling off areas left behind, billions more for services public and tax cuts at the same time.
Tensions started after Mr. Javid won a battle to include rules that limit borrowing Tories' Election Manifesto.
A close ally of Mr. Javid said: “Dominique did not want any tax rules at all.
"No10 didn't understand their need, and they didn't really understand what they signed up for afterwards.
"These conversations have started to get really tough in the past two weeks, as we explained that they couldn't do everything without raising taxes. "
In a personal quirky search for Mr. Cummings, the ally added, "You can change the spads, you can bring in as many data scientists as you want, but in the end the numbers don't lie. "
Allies of Mr. Javid believe stories that made him look bad and the Treasury were also sown in the media by numbers from No. 10, particularly the one where he drew up plans for an annual housing tax on expensive homes.
He was also humiliated when sources downing Street revealed that they called him "CHINO" - Chancellor by name only.
One said there had been "really weird bullshit in the past two weeks."
Another Javid confidant accused Downing Street staff of "undermining the chancellor from the start, informing him that he is weak and pretending that you are driving politics."
They then "introduced process changes so that you can make this weakness a reality."
The former boss of the Treasury blew up the Prime Minister's cabinet reshuffle this week when he resigned, after refusing to allow the Prime Minister to fire his five special advisers and see a No10 / No11 joint economic unit take command of his ministry.
In a backlash on the resignation, the big conservatives also warned yesterday the Prime Minister not to "neutralize" the Treasury during the tremor.

Chair of the Commons Treasury Committee Mel Stride said that the ministry performs "a key function as a steward of public finances".
He added, "It's about control. If it ends up in the kind of space where the Treasury is castrated, it would be more problematic. "
Leaving his home yesterday morning, Mr. Javid refused to join the bitter recriminations.
When asked if he had a message for the Prime Minister, Mr. Javid just smiled and said, "Happy Valentine's Day."
