UK Border Chief Quits as Migrant Boat Crossings Surge

Britain’s top official tasked with tackling illegal Channel crossings is stepping down after failing to curb the crisis.

Martin Hewitt, head of the Border Security Command, will leave his post at the end of March—well before the end of his three-year term—following mounting frustration inside the Home Office over persistently high migrant arrivals. His departure comes after more than 66,000 migrants have crossed the Channel in small boats since Labour took office 19 months ago, with last year alone recording over 41,000 arrivals.

Appointed in September 2024 to deliver on the government’s pledge to “smash the gangs,” Hewitt had been given sweeping powers modelled on counter-terror operations. Yet crossings continued at scale, exposing the limits of enforcement efforts without a credible deterrent.

Insiders said Hewitt had become increasingly frustrated with both operational constraints and a lack of decisive policy backing. He had previously pressed for tougher cooperation from France, including the interception of migrant boats at sea—a measure repeatedly delayed amid political and legal obstacles.

“There was a view that the objectives were not being met, and there needed to be a tighter, more defined operational focus,” one source said.

Home Secretary Shabana Mahmood is understood to have been dissatisfied with the lack of progress, as pressure grows on the government to demonstrate control over Britain’s borders. The issue has also exposed divisions within Labour, with reports of internal resistance to stricter immigration measures and concerns that planned crackdowns may be diluted.

The numbers tell their own story. Crossings rose to one of the highest levels on record last year, while early 2026 figures—though slightly lower—have been attributed largely to poor weather rather than policy success. A much-touted returns deal with France has yielded limited results, with only a small fraction of arrivals sent back—and some reportedly returning to the UK within weeks.

Hewitt will be replaced on an interim basis by Duncan Capps, a former military commander, as the government signals it may seek a more operationally focused figure for the role.

Opposition figures have argued that the failure lies not with officials but with political choices, including the scrapping of the Rwanda deportation scheme and continued legal constraints that limit removals.

“The government’s complete failure on small boats isn’t down to Martin Hewitt. It’s because Keir Starmer and Shabana Mahmood are too weak to take the necessary action,” shadow home secretary Chris Philp said.
