President Joe Biden appealed to world leaders at a Covid-19 summit on Thursday to re-energise a lagging international commitment to attacking the virus as he led the US in marking the “tragic milestone” of one million deaths in the United States.

He ordered flags lowered to half-mast and warned against complacency around the globe.
