Chancellor Rishi Sunak promised to do "whatever it takes to support the economy" in his first Budget as the economic fallout of the coronavirus grows.

Mr Sunak unveiled plans for the "largest fiscal boost for 30 years" as the budget watchdog warned of a gloomier outlook for the economy and higher borrowing.

He announced £30bn of stimulus to boost the economy in the face of the virus outbreak and more than £600bn for infrastructure spending over the next five years. The Chancellor also revealed he will revise the fiscal rules set out by his predecessor, launch a review into business rates and give the NHS an extra £6bn.

"We are doing everything we can to keep this country and our people healthy and financially secure," he told Parliament.

Here are the key announcements made by Mr Sunak in his first Budget:

Economic growth

The Office for Budget Responsibility slashed its forecasts for the UK economy, warning that growth will struggle at 1.1pc in 2020, down from its March 2019 prediction of 1.4pc. The OBR's forecasts did not account for the rapid spread of Covid-19, meaning growth is likely to be much weaker than those predictions.

However, growth will be higher than expected in 2021 at 1.8pc, up from 1.6pc. Growth in 2022 and 2023 will be 1.5pc and 1.3pc, respectively, according to the official spending watchdog.

Mr Sunak said the coronavirus will have a "significant" but "temporary" impact to the economy. He warned a fifth of the working population may be off sick at any one time and that consumer spending will fall. The UK cannot avoid a fall in demand and the country's productive capacity will be hit, the Chancellor warned.
