Newspaper headlines: 'May's transition gambit draws fire'
The Times's lead article suggests Theresa May "faces the most perilous week of her premiership" after "infuriating" her party by raising the prospect of extending the post-Brexit transition.
It says "rival blocs of Conservative MPs" have "stepped up" their "plotting against the prime minister", with a small band said to favour installing David Davis as a caretaker leader.
Brexiteer Tories are said by the Daily Express to be considering tabling an amendment to the finance bill enacting the budget later this month, to ensure Parliament has a say on whether to continue providing funding to the EU after Brexit.

The Guardian reports that "the plastics recycling industry is facing an investigation into suspected widespread abuse and fraud within the export system".
The paper outlines allegations that exporters are falsely claiming for tens of thousands of tonnes of plastic waste that does not exist, and that much of the UK's waste is ending up in rivers and oceans.
Meanwhile, the Daily Mail says many councils will no longer take yogurt pots and other mixed plastic containers, because overseas processing firms refuse to accept them. Local authorities are said to be resorting to burning the waste instead.
The Financial Times reveals that Uber wants to expand to offer temporary workers - such as waiting staff and security guards - for events and corporate functions.
The paper says Uber Works is "the latest attempt by the car-hailing company to diversify its business ahead of next year's potential one-hundred-billion dollar initial public offering".
It says the firm hopes to tempt its large pool of drivers to become contractors as alternative sources of income.
Research cited by the Times is said to suggest that "nature trumps nurture" when it comes to determining whether or not people go to university.
A team who examined the results of identical twins found that genes heavily influenced the quality of the chosen place of study, more so than environmental factors, and the likelihood of achieving a good degree.
And for many pet owners, the loss of their beloved companion is hard to bear. But the Times reports that a French conceptual artist has ensured her feline friend will be forever immortalised, by persuading "some of the world's most popular performers" to make a tribute album.
Bono, Pharrell Williams and Jarvis Cocker are among almost 40 artists who recorded tracks in memory of Sophie Calle's cat Souris, or Mouse.
Several of them are said to have met the black and white cat while he was alive. Whereas others were sent photographs "so they could appreciate his good looks and charming personality".
