A second person has been deported from the UK to France.
An Eritrean man was on board a flight back to the continent in the past hour having illegally entered the UK.
It comes after the person lost a legal challenge against his return to France.
He arrived in the UK on a small boat last month, and comes the day after the first person was sent to France.
The Home Office says the asylum seekers the UK will accept from France in return will be arriving in "the coming days".
Speaking after the first deportation yesterday, Home Secretary Shabana Mahmood said: "This is an important first step to securing our borders. It sends a message to people crossing in small boats: if you enter the UK illegally, we will seek to remove you.
"I will continue to challenge any last-minute, vexatious attempts to frustrate a removal in the courts.
"The UK will always play its part in helping those genuinely fleeing persecution, but this must be done through safe, legal, and managed routes – not dangerous crossings."
As the man was flying across the Channel, the PA news agency reported that hundreds of others were attempting to cross the other way on small boats.
At least one dinghy full of young men made its way to sea from Gravelines Beach northeast of Calais, with a child passed aboard as it went out to sea, according to a reporter present.
The agency also reported that at around 5.30am, another inflatable vessel was launched into a canal by a group of 40 young men who suddenly appeared in from a quiet side street.
Police officers watched from the bank as those on board struggled to keep the boat straight.
A failed attempt earlier in the night ended with a group of men forming a human chain to help haul people out of the mud.
Website Flightradar24 is showing drones above the Channel currently, which is normally the case when authorities are observing crossings.
