Eagle-eyed TV viewers claim Boris Johnson is 'losing his hair' after spotting several strands on the PM's shoulders when he addressed the Commons on Monday.
The Prime Minister told MPs that 'deaths are already rising' and the 'the weeks and months ahead will continue to be difficult and will test the mettle of this country'.
He then returned to television screens this evening to plunge millions of Britons deeper into coronavirus lockdown in his live Downing Street briefing.
While many viewers took to social media to share their shock at the worrying news, others commented on the PM's apparent hair loss - a symptom linked with Covid-19.
