Borrowing more money to invest into the UK is “the right economic thing to do”, the chancellor has said.
Rishi Sunak said that interest rates were at a “multi-decade low” and he was “not going to make an apology” for the Budget – which included included a £30bn package of investment.
The Bank of England announced a cut in interest rates on Wednesday.
But the Resolution Foundation warned of a £575 a year blow to households, even before the impact of coronavirus.
The think tank said the mark down of the UK economy by the Office of Budget Responsibility, without taking the outbreak into account, was “incredibly grim and yet still unbelievably optimistic”.
Labour’s John McDonnell told the BBC’s Today programme he welcomed more investment from the government, but “10 years of austerity brought the country to our knees” and the Budget was “only going part way to making up” for Tory cuts.
The chancellor said the plans he laid out on Wednesday were a “significant step change” for the government and the amount it would invest in infrastructure.
As well as a £5bn emergency response fund for the NHS and a number of other measures to tackle the coronavirus outbreak, he announced spending of over £600bn on roads, rail, housing and broadband across the next five years.
But questioned over the OBR’s low growth forecasts in the short term, Mr Sunak said the organisation had praised the government’s long-term investment plans.
“We can look at that as see we are on the right track with the plans we are doing, and it will start to have an immediate effect on people,” he told Today.
Former Prime Minister Theresa May urged “restraint and caution” on spending after the Budget announcement.
She told the Commons: “Although spending a lot of money may be popular and may seem the natural thing to do, there is, of course, that necessity to have a realistic assessment of the longer term impact of those decisions and of the longer term consequences.
“It is also necessary to ensure that we have that restraint and caution that enables us to make the public finances continue to be strong into the future.”
Mr Sunak defended his plans, saying he would be sticking to the fiscal rules set out in his the Tory’s election manifesto.
“But we are going to take advantage these historically and unprecedented very low interest rates to invest in the long-term productivity of our economy,” he said.
“That is, I think, the right economic thing to do, whilst overall having stable management of our debt.”
Mr Sunak added: “I am not going to make an apology for responding at scale in a comprehensive fashion to the immediate challenges we face from coronavirus. I do think that is the right thing to do.”
