App changes could force more people to self-isolate
More people are to be forced into Covid self-isolation. The NHS contact tracing app's algorithm has been tweaked - lowering the "risk threshold" that determines if a user is to be alerted. The Government said the decision was necessary to tackle rising coronavirus infection rates by breaking the chains of transmission. But the changes to the app - so far downloaded by 19 million people, or about 40 per cent of those with eligible phones - could send many more into de facto lockdown with no ministerial announcement. Read how the technology actually works - and what the "possible exposure" message means.
It comes amid growing speculation of a new national lockdown. Senior figures have told Prime Minister Boris Johnson it is becoming clear that even Tier 3 restrictions do not go far enough and warned that, at current infection rates, most of the country would be under maximum measures within weeks (this is what that means for your daily life). Science Editor Sarah Knapton says Downing Street is considering a Christmas window where families will be able to meet, with lockdowns either side of the festive period. The PM has so far refused to impose any new nationwide restriction, despite lockdowns in France, Italy and Germany where infection rates are lower. These charts show how our numbers compare to the worst hit European nations. Matt is away, but Davey has today's political cartoon - imagining Mr Johnson's Christmas preparations.
Shaming of Jeremy Corbyn sparks Labour civil war
Jeremy Corbyn's allies have accused Labour leader Sir Keir Starmer of "inciting war" by suspending him. The former party leader mobilised supporters against his successor as MPs, unions and members loyal to him demanded his reinstatement and reopened the party's anti-Semitism row. The Equality and Human Rights Commission found failures to tackle discrimination under Mr Corbyn's leadership. Some union figures are discussing the possibility of forming a breakaway party. In our sketch, Madeline Grant says the fact that Corbyn ultimately doomed himself is a matter of irony so delicious that only the most expansionary ultra-Zionist could fail to notice it.

Tracey Emin: 'I have the cancer that killed my mother'
She has never cared for privacy; "oversharing" is the point of her art. There is an irony, then, to what happened to Tracey Emin just as the Covid crisis approached. Alone, at home, she was facing death. The diagnosis was squamous-cell bladder cancer. You may not have heard of it, but Emin had. "My mother died of the same cancer," she says. "Four years ago today." Read her exclusive interview with Jessamy Calkin in which she contemplates death, regrets and her next chapter. Columnist Claire Cohen says Emin paints a picture of female pain like no other.
