LONDON — Prime Minister Andy Burnham’s government said the U.K. is willing to discuss American concerns over its digital services tax amid renewed pressure from the White House.

President Donald Trump in June threatened to impose 100 percent tariffs on European countries with DSTs which target U.S. tech firms, and in an interview with The Times newspaper published on Monday, Trump’s top trade official Jamieson Greer said the threat was “not a bluff” and the president’s demands that foreign governments abandon such taxes were “quite serious.”

“We remain open to discussing U.S. concerns and working with partners internationally,” a U.K. government spokesperson said when asked about Greer’s comments.

“This tax is about making sure that businesses pay their fair share of U.K. tax based on the value they derive from U.K. activities,” the spokesperson said, adding that the U.K. is committed to removing it “once a global solution is in place.”

The DST raised over £1 billion last year, predominantly from American tech firms, and has repeatedly drawn Trump’s ire.

The U.K. government has so far resisted calls to abandon the tax, including during trade negotiations last year. A U.K.-U.S. Economic Prosperity Deal signed by Trump and Burnham’s predecessor, Keir Starmer, did not mention the DST but said both sides would continue discussions to increase digital trade and address non-tariff barriers.

Greer added in his interview with The Times that the U.S. administration would not “set artificial timelines” and that relations with his British counterparts, including Trade Secretary Jonathan Reynolds and the prime minister’s business adviser Varun Chandra, are positive.

LONDON — The U.K. capital’s transport authority has granted approval for Wayve and Uber to begin giving rides to members of the public in autonomous vehicles.

Transport for London (TfL) said it licensed 15 modified vehicles operated by the companies, which have a partnership, as “Private Hire Vehicles” (PHV) on a trial basis.

In a statement, London-based startup Wayve said the licenses were “an important step forward” that will allow it to begin giving rides to a small number of passengers later this summer ahead of a full public launch.

Wayve said its vehicles “are designed to operate autonomously, and will do the driving,” though under TfL’s rules, a licensed PHV driver must be present and responsible for the vehicle at all times.

“Safety is our top priority,“ a TfL spokesperson said. “Any new vehicle licensed to carry passengers on London’s roads must align with our Vision Zero goal of eliminating all deaths and serious injuries from collisions on London’s streets by 2041.”

Successive U.K. governments have sought to make the country a European pioneer in self-driving technology.

The Department for Transport opened a permitting scheme for companies to operate commercial robotaxi services without a human driver in May. Applications for that scheme — which is separate from TfL’s PHV regime — continue to be assessed by central government with input from local transport authorities including TfL.

Getting licenses isn’t the only obstacle facing robotaxi services. A survey by the London Assembly’s Transport Committee this month identified widespread opposition to autonomous passenger vehicles among the capital’s inhabitants, with just 29 percent of Londoners saying they support the roll out.
