The first migrants are set to be deported today on passenger flights under the proposed one-in, one-out returns deal with France.

Under the agreement with the French Government, the first asylum seekers are expected to be escorted by contracted Home Office security staff on commercial flights run by Air France.

The first removals are expected to be more “low-key”, compared to the deportations of 47 Albanian criminals and illegal migrants in February.

Migrants who are being deported will join tourists and business travellers on an Air France flight, barring any last-minute legal challenges.

A message sent by the Home Office seen by the Sunday Times told proposed deportees their Air France flight will depart from London Heathrow Terminal 4.

The formal removal direction notice gives a migrant five days’ notice of the Home Office’s intention to deport them, allowing them to seek final legal advice before any removal can take place.

Secure vans will then transport them from the Harmondsworth immigration removal centre next to Heathrow airport, where they have been detained since arriving on small boats last month.

Legal observers told The Telegraph there might be as few as 10 migrants per flight, with at least one security escort per migrant.

The number of migrants arriving in the UK after crossing the English Channel has topped 30,000 for the year so far.

It is the earliest point in a calendar year at which the 30,000 mark has been passed since data on the crossings was first reported in 2018.

The “one in, one out” pilot scheme has been agreed for the UK to send back to France migrants who have crossed the Channel, in exchange for those who apply and are approved to come to the UK.

A Home Office spokesman said: “Under the new UK-France treaty, people crossing in small boats can now be detained and removed to France. We expect the first returns to take place imminently.

“Protecting the UK border is our top priority. We will do whatever it takes to restore order to secure our borders.”
