The number of people landing on England's southern beaches after making the dangerous Channel crossing fell by a third in 2023, but the latest numbers on a government website showed 10,170 arrived between January and May 25, up from 7,395 over the same period last year.

"We continue to work closely with our French partners to prevent crossings and save lives," an interior ministry spokesperson said in response to the surge in numbers.

Rishi Sunak, who announced the election date on Wednesday, said later this week that asylum seekers who come to Britain illegally would not be deported to Rwanda before the vote.

The plan has been bogged down by legal obstacles for more than two years, and the opposition Labour Party, which is about 20 points ahead in opinion polls and seen on track to end 14 years of Conservative rule, has promised to scrap the policy if it wins the election.
