Civil servants who let sex offender migrants in face sackings and pension loss under Reform UK

Civil servants found to have committed such offences would face further sanctions, including being forced to forfeit their pensions and undergoing gross misconduct dismissal proceedings.

A dedicated police task force, supported by the National Crime Agency, would be established to investigate offenders.

Reform UK’s Head of Policy, Zia Yusuf, told The Telegraph that a Reform Government would review cases spanning the past decade.

He said: “The first duty of any government is to keep its citizens safe. On that most basic test, both Conservative and Labour governments have failed — and they have failed knowingly.

“What we are witnessing is not a system stretched to breaking point by accident, but one in which safeguards have been deliberately abandoned, laws disregarded, and responsibility systematically evaded.

“Civil servants inside the Home Office have been waving through asylum claims for foreign nationals with known histories of sexual offending. That is not a grey area.

“Granting asylum to those who are likely to cause harm to British people is unlawful under the immigration rules, and yet it has been allowed to continue unchecked for years.

“The result is that the British state itself has become complicit in endangering women and girls. That must end.”

Under the proposals, foreign national sex offenders would be barred from entering the UK, and any asylum seekers previously charged with sex offences would be deported.

The announcement comes just a month after a Home Office whistleblower claimed that migrants accused of sex offences and other crimes were being granted asylum regardless of their criminal history.

The caseworker said Home Office staff were able to approve asylum claims from individuals charged with crimes, provided the offence did not carry a prison sentence of more than 12 months.

Abdul Ezedi, the Clapham chemical attacker, was granted asylum in the UK despite having received two suspended jail sentences.

Both sentences were for less than 12 months and related to sexual assault and indecent exposure.

The 31-year-old Afghan national attacked a woman and her children with a corrosive substance last year, causing life-changing injuries.

Following a manhunt, his body was later found in the River Thames.

A Home Office spokesman said the department takes all allegations seriously and is “committed to addressing any concerns appropriately”.

They added that it does “not accept the characterisation of these concerns as presented”.

The spokesman said: “The integrity of the UK immigration system is paramount. We operate within a robust framework of safeguards and quality assurance measures to ensure all claims are thoroughly assessed, decisions are well-founded, and protection is granted only to those who meet the established criteria.”

A Government spokesman added: “Civil servants do vital work securing UK borders and processing returns so that foreign national offenders are removed from our streets.

“Since the Government came into power, we have removed nearly 50,000 people with no right to be on British soil, and asylum-related returns are up 27 per cent compared with the previous year.

“We will not allow foreign criminals and illegal migrants to exploit our laws. We are reforming human rights legislation and replacing the broken appeals system so we can scale up deportations.”
