Rishi Sunak faces a revolt in the UK Parliament over his Rwanda plan after a grilling on COVID-19

LONDON (AP) — U.K. Prime Minister Rishi Sunak faced a rebellion from restive lawmakers over his signature immigration policy, while fending off tough questions Monday about his judgment during the COVID-19 pandemic.

The twin pressures add up to one of the toughest weeks of Sunak’s 13 months in office, with both his present authority and past record at stake.

Legislation intended to salvage Sunak's blocked plan to send asylum-seekers to Rwanda faces a vote in the House of Commons on Tuesday. While disparate groups of Conservative lawmakers met in Parliament to pick holes in the bill, Sunak was undergoing a six-hour grilling at the U.K.’s , where he denied taking risks with public health.

Sunak was Treasury chief to Prime Minister when the pandemic hit, and backed a discount initiative that encouraged people to go back to restaurants in August 2020 after months of lockdown.

The government’s scientific advisers have told the judge-led inquiry that they weren't informed in advance about the “Eat Out to Help Out” program, which scientists have linked to a rise in infections. One senior government science adviser referred to Sunak in a message to colleagues at the time as “Dr. Death.”

Sunak denied there had been “a clash between public health and economics" when it came to confronting the pandemic, which authorities said left more than 230,000 people dead in the U.K.

He said that he saw his role “as making sure the prime minister had the best possible advice, information and analysis relating to the economic impact” of potential measures. He stressed that Johnson, as prime minister at the time, was ”the ultimate and sole decision-maker.”

At the inquiry last week, he'd wanted to let the virus “rip” through society.

Sunak denied seeing a warning from government scientific advisers in late June 2020 about the risks of opening up society. He defended his decision not to consult scientists about the “Eat Out to Help Out” plan, saying the government “had already made the collective decision to reopen indoor hospitality.” He said the policy had helped save the livelihoods of low-paid bar and restaurant workers.

Sunak began his testimony by apologizing to everyone who suffered during the pandemic and said it was important to “learn the lessons so that we can be better prepared in the future.”

His evidence didn't, however, include his WhatsApp messages from the time. Sunak claimed they had been lost during several changes of phone since then.

Johnson also has been unable to produce messages from several key months in 2020, saying they are on an old phone for which he has forgotten the password and tech experts have been unable to retrieve them.

Naomi Fulop from the pressure group COVID-19 Bereaved Families for Justice said that Sunak's evidence showed he was a “public health hazard.”

“Over and over again today, Sunak claimed he could ‘not recall’ key moments from his time as chancellor. The public does,” Fulop said.

Meanwhile, Sunak is battling to save the Rwanda plan, a key part of his pledge to stop from trying to reach England from France in small boats. More than 29,000 people have done so this year, down from 46,000 in all of 2022.

The plan has already cost the government 240 million pounds ($300 million) in payments to Rwanda, which agreed in 2022 to process and settle hundreds of asylum-seekers a year from the U.K. But no one has yet been sent to the country, and last month the U.K. Supreme Court ruled the plan illegal, saying Rwanda isn't a safe destination for refugees.

In response, Britain and Rwanda for migrants. Sunak’s government argues that the treaty allows it to declaring Rwanda a safe destination, regardless of the Supreme Court ruling.

The law, if approved by Parliament, would allow the government to “disapply” sections of U.K. human rights law when it comes to Rwanda-related asylum claims.

The bill has faced criticism from centrist Conservative lawmakers concerned that it sidelines the courts, though a major centrist faction, the One Nation group, said Monday that it would support the bill.

But legislators on the party’s authoritarian wing think the legislation is too mild because it leaves migrants some legal routes to challenge deportation, including at the European Court of Human Rights.

The hard-line European Research Group of Conservative lawmakers said that the bill “provides a partial and incomplete solution” and needs major changes. Group member Mark Francois urged Sunak to rework the bill before putting it to a vote, but didn't say whether he would vote against it if that didn't happen.

If the bill passes Tuesday's vote, weeks of wrangling and more votes in Parliament lie ahead. Defeat would leave the Rwanda plan in tatters, and would threaten Sunak’s leadership.

Sunak believes delivering on his promise to “stop the boats” will allow the Conservatives to close a big opinion-poll gap with the opposition Labour Party before an election that must be held in the next year.

But some Tory lawmakers think he is bound to fail, and are contemplating a change of leader. Under party rules, Sunak will face a no-confidence vote if 53 lawmakers — 15% of the Conservative total — call for one.

Others argue that it would be disastrous to remove yet another prime minister without a national election. Sunak is the third Conservative prime minister since the last election in 2019, after the party ejected both Johnson and his successor, Liz Truss.

Lawmaker Damian Green, a leading Conservative moderate, said that anyone who wanted to change the party leader again is “either mad, or malicious, or both.”
