Rescue boats from both France and the UK took part in the operation to evacuate passengers from the stricken vessel.

More than 150 migrants travelling to the United Kingdom in a boat across the English Channel have been rescued after the vessel caught fire.

A major rescue operation was launched on Tuesday morning near the French port of Boulogne-sur-Mer, with both French and British authorities working to evacuate those on board, some of whom had jumped into the sea.

The local French maritime prefecture said five of the 157 people on board had requested rescue overnight and were evacuated. It said the remaining passengers refused assistance and the boat continued its journey towards the UK, until the engine caught fire and all those on board were rescued.

Since Andy Burnham became UK prime minister two weeks ago, more than 2,000 people have crossed the English Channel in small boats.

Immigration is an extremely divisive and hotly contested issue in the UK, prompting Burnham to pledge that he will be “relentless” in stopping people from reaching the country in small boats.

A person generally must be in the UK to lodge an asylum application, as current rules do not allow people to make asylum claims from overseas. Amnesty International has argued that this makes it “impossible” for people abroad to seek asylum in the UK.

The 1951 United Nations Refugee Convention, to which the UK is a signatory, establishes protections for people fleeing persecution and recognises that those seeking safety may have to use irregular routes.

Reform UK leader Nigel Farage commented on the incident in the English Channel in a post on X.

“We must put a stop to this. Our plan will save lives,” he said.

Farage’s party has pledged to abolish what is known as indefinite leave to remain (ILR) if it wins the next election, due to take place in 2029. ILR allows people to live and work in the UK without a time limit. Reform has also said it would rescind existing ILR grants.
