In a dire assessment at tonight's Downing Street press conference, Brits were warned deaths in the second wave could be twice as bad as in the first, with thousands of deaths a day.
Hospitals would run out of capacity within weeks and doctors forced to choose between "who would live and who would die", the PM said.
Mr Johnson had previously described a new national lockdown as the "nuclear option", but the new restrictions will hit England until December 2.
The Commons will vote on the new restrictions this week before they come into force, with some MPs hinting they may vote against them.
MP LOCKDOWN FURY
Former Brexit Secretary David Davis told Times Radio: "I want Parliament to make this decision and [MPs] to be properly briefed.
"This is a bigger decision than going to war from the point of view of many people in the country.
"We need to really be very clear about what our exit strategy is."
He warned his vote was not guaranteed - and many of his colleagues were sceptical too.
Shambolic. Rudderless ramblings. Constituents getting in touch furious or in tearsBackbench Tory MP
Following confirmation of a lockdown to tackle the spread of the virus, one Tory MP raged to Times Radio's Matt Chorley: “Shambolic. Rudderless ramblings.
"Constituents getting in touch furious or in tears.”
Another MP branded the PM's lockdown as "grim grim grim”, while another said: "I think it could be his Suez”.
Tory MP Desmond Swayne told MailOnline: ‘I don’t doubt it is a difficult decision, but that doesn’t alter it being the wrong decision.
"The things that it does to our economy our health and everything else is worse than the disease they are combating."
Andrew Bridgen suggested he too would not support the government's new restrictions.
He said: "These are huge decisions that the government has to make with enormous economic and political ramifications.
"The Sage so-called experts won’t be held to account for the correctness of their decisions at the next general elections. We will."
But other MPs regarded as lockdown sceptics sympathised with the PM.
Former Cabinet minister Steve Baker said: "It is clear the Prime Minister and the Cabinet face exceptionally difficult choices.
"Please listen carefully to the Prime Minister.

"We will all need to think forward several weeks to the circumstances we could face on coronavirus, on health more widely and for people's livelihoods."
It comes as Britain today passed one million Covid cases after 21,915 more people positive for the bug.
Another 326 deaths have been recorded, meaning 46,555 have now died of coronavirus in the UK.
Under the tough new lockdown rules unveiled tonight, all non-essential shops must close as England goes back into a national lockdown for a month.
Pubs and restaurants will shut but will be allowed to do takeaways and deliveries.
Schools, colleges and universities will all remain open and unlimited exercise will be allowed, but holidays abroad are to be banned.
Overnight stays will also be prohibited, with a nationwide ban on people mixing indoor, and all travel apart from work discouraged.
But the furlough scheme will be extended with 80 per cent of pay.
Giving a gloomy outlook going into winter, Mr Johnson said: "In this country alas as across much of Europe the virus is spreading even faster than the reasonable worst case scenario of our scientific advisers
"Whose models as you’ve just seen now suggest that unless we act we could see deaths in this country running at several thousand a day
"A peak of mortality alas far bigger than the one we saw in April."
Meanwhile, Labour leader Sir Keir Starmer called for tonight for the second national lockdown to start straight away.
