“I will be setting out our plan to shape the economy for the future and triggering the start of our infrastructure revolution,” Javid said in a statement.
In the event of a no-deal Brexit, the government would act quickly to outline its approach and “take early action to support the economy, businesses and households,” followed by a budget in the following weeks, the government said.
Prime Minister Boris Johnson says he will take Britain out of the EU on Oct. 31, with or without a deal. But lawmakers have passed legislation which they say will force him to seek a delay if no transition agreement is struck in time.
Javid, who took office in July, has already announced the biggest increase in day-to-day public spending in 15 years, putting borrowing on course to overshoot a cap set by his predecessor, Philip Hammond.
Javid has suggested he is prepared to borrow more in the future to take advantage of record-low borrowing costs.
Britain has steadily cut its budget deficit from almost 10% of gross domestic product in 2010 to just under 2% now.
But analysts have warned that Javid could end up weakening Britain’s budget credibility by making big spending pledges at a time when the economy has slowed and the outcome of Brexit remains so unclear.
