If an illegal migrant woman gives birth to a child fathered by a British citizen, the baby is automatically British. The mother can then apply for a family visa, remain in the UK, and eventually apply for UK citizenship. Scammers are touting for British men on Facebook and offering them £10,000 to add their names to birth certificates to help pregnant migrants stay in the UK. Facebook says its rules ban this. A BBC investigator posing as an illegal pregnant migrant was told by an agent he had British men who could be fake fathers in a ‘full package’ for £11,000, saying the process is ‘very easy’ and he would get the child a UK passport and ‘concoct a convincing backstory to successfully dupe the authorities’.
