THERESA May's government was last night forced to accept a raft of opposition amendments to the Budget amid ongoing uncertainty over its pact with the DUP.
Labour claimed the British prime minister was "in office but not in power" and her government was "falling apart" after the Tories avoided triggering any Westminster votes by supporting the four amendments to the Finance Bill.
The amendments included SNP calls for a review of the public health effect of gambling, while Labour's included seeking a report detailing the impact of measures to require disclosure of information about certain cross-border tax arrangements under different Brexit scenarios.
The government climbdown and unwillingness to force votes came after the DUP voted with Labour once and abstained five times during Finance Bill votes on Monday.
The move, prompted by DUP opposition to draft Brexit withdrawal deal, put strain on the confidence and supply arrangement struck in June 2017.
Shadow chancellor John McDonnell said it was "absolutely staggering" that the government accepted all Labour amendments because it couldn't rely upon the DUP's support.
"The Tories are in office but not in power – we're watching a government falling apart in front of us," the shadow chancellor said.
Meanwhile, Lady Sylvia Hermon, the only pro-Remain MP from the north sitting at Westminster, has said the proposed withdrawal agreement does not threaten the integrity of the UK, as claimed by the DUP.
Following a meeting with Mrs May on Monday, the North Down MP said a clause in the draft deal actually secured the north's place in the union and she said it would helpful if the same sentiment were reflected in all subsequent statements from the EU.
Lady Sylvia said she had told the prime minister that she would be "inclined" to back the deal in parliament.
