High levels of legal migration have for more than a decade dominated Britain's political landscape, and will be a key battleground again in the vote which is expected next year.
For the year ending December 2022, the ONS revised up the net migration figure to 745,000, a new record high and up 139,000 on its previous estimate.
It also said the net migration number for the year ending June 2023 was 672,000, up from 607,000 a year earlier.
"The government remains completely committed to reducing levels of legal migration," he said in a statement.
