Aircraft-engine maker Rolls-Royce is reporting a plunge into the red as the collapse in air travel takes its toll, APA reports citing BBC.
Boss Warren East says 2020 had been "unprecedented", with the company making a loss of almost £4bn, after a £583m profit the year before.
The company makes most of its money servicing engines, and the Covid-driven fall in airline travel has slashed revenues.
The firm has cut jobs and raised cash from investors to bolster its finances, but expects to burn through another £2bn this year as it restructures its business.
