LONDON (AP) — U.K. Prime Minister Rishi Sunak faced heavy pressure from his own Conservatives to take swift action to bring down migration, as new data published Thursday showed net migration numbers were higher than previously thought. The Office for National Statistics revised its estimates for net migration to the U.K. — meaning the number of people arriving minus those leaving — in the year to December 2022 to 745,000. That is a new record and significantly higher than the previous estimate of 606,000 for the same period.
