Theresa May's claim that "austerity is ending" was met with laughter by MPs as the prime minister clashed with Jeremy Corbyn at Prime Ministers Questions.
Condemning what he called a "broken promise Budget", the Labour leader demanded to know why the government had not pledged to end the benefit freeze.
That prompted confusion over Labour's own policy on the issue after a spokesman for Mr Corbyn said the party would not necessarily raise benefits in line with inflation, despite John McDonnell, the shadow chancellor, having said it would.
The Tories were later engulfed by confusion of their own after Downing Street refused to endorse Brexit secretary Dominic Raab's suggestion that an agreement with the EU was likely to be in place by 21 November.
As Britain prepares to leave the EU, Jeremy Hunt, the foreign secretary, announced plans to recruit 1,000 more diplomatic staff.
His predecessor, Boris Johnson, was also in the news after it emerged that he had accepted an all-expenses-paid trip to Saudi Arabia just two weeks before the murder of journalist Jamal Khashoggi.

Speaking at the Policy Exchange think-tank, Jeremy Hunt said he wanted business leaders to become UK ambassadors as part of efforts to "reinvigorate and expand British diplomacy".
Responding to questions about whether this risked a system of "cronyism", he said:
"There will be absolutely no conflict of interest allowed and anyone applying for these jobs will apply through normal Foreign Office processes so we can make sure that proper independence is protected."
"There may be one or two posts where someone who is perhaps chief executive of a FTSE company, who has got strong links with another country, could do a brilliant job representing the UK, building up our trade with another country.
"We want the Foreign Office to be open to that kind of talent."
Sir David Natzler, chief clerk of the Commons, has said MPs could vote twice on the deal the government secures with the EU.
He told the Brexit committee that a parliamentary rule that says there should not be a vote on exactly the same matter twice in the same sitting was not designed to "obstruct the necessary business of government on such a crucial thing".
British and Canadian politicians have written to Facebook founder Mark Zuckerberg to demand he explain his company's "failures of process" in relation to the spread of fake news and propaganda.
Damian Collins, the Tory MP who chairs the Commons digital, culture, media and sport select committee, has joined forces with Bob Zimmer, chair of the Canadian parliament's committee on access to information, privacy and ethics, to announce an "international grand committee" on "disinformation and fake news".
They told Mr Zuckerberg:
"Over the past year, our committees have both sought evidence from a Facebook executive with sufficient authority to give an accurate account of recent failures of process, including the recent Cambridge Analytica scandal and subsequent data breaches.
"You have chosen instead to send less senior representatives, and have not yourself appeared, despite having taken up invitations from the US Congress and Senate, and the European Parliament."
If there is hard Brexit, a chaotic situation that will inflict unprecedented damage on the economy, the public spending increases and tax rises will not be reversed in the short term simply because the economy will require life support
Speaking to the Commons Brexit committee, chief clerk Sir David Natzler said amendments tabled by MPs to the government's plan in the case of a no-deal Brexit would have no legal effect - as reported by The Independent at the weekend...
David Davis appears to have backtracked on his comments last night, in which he suggested Theresa May would get her Brexit deal through Parliament because "terror will win". He's just tweeted to say that, in fact, he doesn't think the Chequers plan would command a majority in the Commons...
Jeremy Corbyn is up. He also mentions the Pittsburgh attack, which he says was "disgusting, depraved and appalling".
The Labour leader says that if he was a prison governor, a local government leader or a head teacher, he would be preparing for "more difficult years ahead". He asks Theresa May if she thinks that analysis is wrong.
May says the Budget proved that austerity is ending, saying this is about "continuing to bring debt down and put more into our public services".
