UK's Sunak says coronavirus aid will be on an "unimaginable" scale

British finance minister Rishi Sunak said the coronavirus outbreak would require government support on a previously unimaginable scale, starting with 330 billion pounds ($398 billion) of loan guarantees for businesses.

"This struggle will not be overcome by a single package of measures or isolated interventions," he said at a news conference. "This national effort will be underpinned by government interventions in the economy on a scale unimaginable only a few weeks ago."
