British finance minister Kwasi Kwarteng today brought forward the publication of fiscal plans and economic forecasts to October 31.
The Minister is under pressure to rebuild shattered investor confidence in the new government's economic agenda.
The plan had previously only been due on November 23 after a"mini-budget" in September when Kwarteng triggered a rout in British bonds by announcing £45 billion of tax cuts but providing no details of how they would be funded.
Earlier today, the Bank of England enlarged its emergency support for the shaky government bond market, ahead of the package's expiry on Friday.
Kwarteng said the new date for his medium-term fiscal statement would allow the independent Office For Budget Responsibility (OBR) enough time to assess updates to official data and for a full forecast process to take place.
He and Prime Minister Liz Truss are hoping that the OBR will back their claims that the combination of tax cuts and reforms to areas such as planning rules and immigration will boost Britain's economic growth prospects.
The new date will also allow the Bank of England to understand the government's tax and spending plans before it announces its next interest rate decision on November 3.
Last month the International Monetary Fund said the government's push for economic growth and the Bank of England's attempts to control inflation were working against each other.
Kwarteng is due to attend the IMF's semi-annual meeting of global policymakers in Washington this week.
Kwarteng has previously said the OBR would not have had enough time to produce satisfactory forecasts for his September 23 announcement, although the OBR has contradicted this.
Junior Treasury minister Andrew Griffith said market practitioners he had spoken to received news of the new date for the fiscal statement warmly. British government bonds and the pound showed scant reaction, with both in decline today.
The new date leaves Kwarteng and Truss with little more than two weeks to settle divisions in her cabinet over cuts to government spending.
Having already bowed to pressure to drop the most divisivepolicy - eliminating the 45% top rate of income tax for the highest earners - they face cabinet opposition to the idea of cutting welfare benefits in inflation-adjusted terms.
Last week two senior ministers expressed their dissatisfaction with Truss's income tax U-turn, suggesting that unity among her top team was breaking down.
The Financial Times reported today that as part of her attempts to stabilise financial markets, Truss had changed her mind about appointing someone to lead Britain's finance ministry who had no experience of working there.
Truss was no longer expected to appoint Antonia Romeo to run the Treasury, the FT said, citing senior government figures.
