Boris Johnson has rejected pleas to hold an emergency budget now to fight the cost-of-living spiral hitting Brits this Autumn.
Downing Street said it will be for the next Prime Minister - who only takes office in a month - to decide any new help for Brits to pay energy bills.
No10 also dismissed ex-PM Gordon Brown’s plea for COBRA to sit in “permanent session” as the economic storm is unleashed.
And the PM’s spokesman said there were no plans to recall Parliament. He said it would be "inappropriate" to say if more needs to be done to help Brits.
It comes after the PM and his wife Carrie enjoyed a mini-moon at a “soothing energies” mountain villa where guests dine on bear while officials predicted the worst recession since the 1990s.
The lame duck Prime Minister returned last night after four nights at Vila Planinka in Slovenia, which urges guests to ditch their phones and laptops in rooms costing £242 to £542 a night.
While they were away, the Bank of England forecast inflation would hit 13% this year, while the economy will shrink for five quarters and could dive by 2.1%.
Labour and Lib Dem politicians blasted the PM - who has only a month left in office - for taking his break despite calls for an emergency budget or even to recall Parliament.
Writing exclusively for Monday's Mirror, Gordon Brown urged ministers to convene rolling meetings of the Whitehall emergencies panel that meets in a Westminster bunker - usually after terror attacks, major floods or other disasters.
Mr Brown wrote: “COBRA, the government’s disaster emergency committee, should be in permanent session to deal with the coming fuel and energy crisis.
“Even if Boris Johnson has now gone on holiday, his deputies should be negotiating hard to buy new oil and gas supplies from other countries and they should be urgently creating the extra storage capacity that we currently lack.”
But asked about Mr Brown's plea, Boris Johnson's official spokesman said: "Clearly these global pressures mean challenging times for the public.
"The government recognised that the end of the year will bring wider challenges with things like changes to the price cap.
"That's why... we introduced a number of measures to help the public - several million payments of the first part of the £650 cost of living payment [to benefit claimants] have been made.
"In October, everyone will see £400 start to come off their energy bills in a phased way. Nearly one in 10 people will get a £150 disability payment.
"And millions of pensioner households will see an extra £300 through their winter fuel payments in November and December.
"Now clearly, some of the global pressures have increased since that was announced.
"You'll understand that by convention, it's not for this Prime Minister to make major fiscal interventions during this period. It would be for a future Prime Minister."
Asked if the PM could sit down with the two candidates and work out an emergency package for the Autumn, No10 replied: "There are no plans for that to happen. It will be for a future Prime Minister to decide whether or what measures are required."
Asked if Chancellor Nadhim Zahawi was quietly drawing up plans ready for the next PM, he replied: "I’m not aware of the Chancellor doing specific work.”
Earlier a minister was forced to deny the Government was “in limbo” after the PM and Chancellor were on holiday.
Sports Minister Nigel Huddleston said: "I wouldn't say it's in limbo actually, there's still a lot of ministers still doing their job. It's summertime, a lot of the people are on holiday, a lot of people work very, very hard."
The row broke as allies of the Tory leadership candidates continued to clash over their economic plans.
Rishi Sunak slammed Liz Truss ' plans to rush through a National Insurance cut as a 'big bung' to rich, because it will save minimum wage workers just £59 a year.
Ex-Cabinet minister Brandon Lewis, who is backing Liz Truss, defended her plan for tax cuts, which experts also fear would fuel runaway inflation.
But asked nine times, he refused to say if she would give “handouts” - cost-of-living payments - to people who need them, instead saying her focus was to cut tax.
Mr Sunak’s ally Oliver Dowden predicted more cost-of-living help will be needed this winter as bills are set to top £3,200 a year.
“It's a false premise to argue that you can't deal with inflation, whilst making sure that people are better off at the same time,” he said.
