(Reuters) – British finance minister Rishi Sunak will use the budget next week to level with the public over the “enormous strains” in the country’s finances, warning that a bill will have to be paid after further coronavirus support, according to an interview with the Financial Times.

Sunak told the newspaper there was an immediate need to spend more to protect jobs as the UK emerged from COVID-19, but warned that Britain’s finances were now “exposed.”

UK exposure to a rise of one percentage point across all interest rates was 25 billion pounds ($34.83 billion) a year to the government’s cost of servicing its debt, Sunak told FT.

“That (is) why I talk about leveling with people about the public finances (challenges) and our plans to address them,” he said.

The government has already spent more than 280 billion pounds in coronavirus relief and tax cuts this year, and his March 3 budget will likely include a new round of spending to prop up the economy during what he hopes will be the last phase of lockdown.

He is also expected to announce a new mortgage scheme targeted at people with small deposits, the UK’s Treasury announced late on Friday.

Additionally, the government will also announce a new 100 million pound task force to crack-down on COVID-19 fraudsters exploiting government support schemes, it said.
