We've just been hearing from the prime minister's spokesperson at a Lobby briefing for political journalists.
As part of the questioning, Number 10 confirmed a second small boat migrant deported under Labour's one in, one out policy had crossed the Channel again to return to the UK for a second time.
The spokesperson said the person would be sent back again as soon as possible.
The government has claimed the system is working as the biometric checks they have introduced can spot people crossing for a second time.
A Home Office Spokesperson said: "Anyone looking to return to the UK after being removed under the UK-France agreement is wasting their time and money.
"This individual was detected by biometrics and detained immediately. His case will be expedited, and he will be returned to France as quickly as possible.
"The message is clear: if you try to return to the UK you will be sent back. We will do whatever it takes to scale up removals of illegal migrants and secure our borders."
