British Prime Minister Rishi Sunak is committed to reducing net migration to the UK from record highs, his spokesman said on Thursday, adding that the government would consider all options to ensure the system was functioning properly.

“The prime minister is fully committed to bringing overall numbers down,” his spokesman said after official statistics showed net migration rose to an estimated record of 504,000 in the year to June.

“We’re considering all options to make sure the immigration system is delivering.”
