Good morning. Another politically tumultuous week for Britain, an unprecedented ending to the APEC summit and a letter from our Asia editor. Here’s what you need to know:

• Theresa May: ‘The next seven days are critical’

The British prime minister, after days of political turmoil, said in a TV interview that she would head back to Brussels this week and European leaders are scheduled to discuss a draft Brexit agreement on Sunday. But anything can happen before then to upend the process.

The deal, though reluctantly approved by her cabinet last week, prompted widespread criticism in Britain and looks unlikely to get a sign-off from Parliament. Above, anti-Brexit protests in London.

Mrs. May now faces a series of threats at home:

→ A leadership challenge: A secretive panel called the 1922 committee, helmed by Graham Brady, has been collecting letters from members of Mrs. May’s own party stating they’ve lost confidence in her. If the committee receives 48 letters, it can trigger a no-confidence vote.

→ More resignations: Two cabinet ministers have already quit over the deal, including Dominic Raab, the chief Brexit negotiator. If more step down, Mrs. May’s ability to carry on may be called into question.

→ A second referendum: A vote on the terms of the deal and the option to remain in the E.U. is gaining momentum.

And today’s phrase of the day is poison-pen letter: A malicious and usually anonymous statement, like the ones being collected by the 1922 committee.

• Indian government hands out free phones for votes.

It seemed too good to be true: a smartphone in every home. Free.

The program, spearheaded by local governments, started in July and has so far handed out 2.9 million phones, in an effort to bridge the country’s yawning digital gap and connect more people to the internet. Above, a group gathers around a new smartphone.

But with election season around the corner, local officials from the country’s ruling party, the B.J.P., are using the phones to target voters.

Contractors have been calling recipients of the phones to ask whether they plan to vote and which party they intend to vote for, according to half a dozen people who made or received the calls. The phones even come pre-loaded with campaign apps.

“They are misusing state machinery for personal gains,” said one worker.

• C.I.A.: Saudi crown prince ordered Khashoggi killed.

The intelligence agency had always been hesitant to definitively point fingers in the killing of the journalist Jamal Khashoggi.

But two sets of communications swayed the agency: intercepts of Crown Prince Mohammed bin Salman’s calls in the days before the killing, and calls by the kill team to a senior aide immediately after.

Based on that and the scope of the crown prince’s control of Saudi Arabia, the C.I.A. went from believing the crown prince, above, was culpable in the killing to believing he ordered the brutal hit job, according to American officials.

The agency’s new assessment adds pressure on the Trump administration to punish the kingdom, a longtime American ally and the centerpiece of its Middle East policy.

Our video team recreated how the killing unfolded at the Saudi consulate in Turkey last month.

• Developers circle a rural patch of Hong Kong.

The wetlands, hemmed by the skyscrapers in Hong Kong and the Chinese city of Shenzhen, are home to rare birds, traditional shrimp ponds and eucalyptus trees — a lush respite from the city’s bustle.

But in a city where land prices are among the highest in the world, it’s also a contentious battleground between environmentalists and property developers.

For decades, landowners have sought — and failed — to develop the area, as preservationists pushed back.

But the people who visit the area, often cyclists and nature lovers, fear that the development companies will eventually win out.

“People in Hong Kong only care about the economy,” said one cyclist.
