I think you might be misunderstanding this.According to the Government’s own figures (as below) I can see a very easy way to save £9.4bn, not just £6bn. In these difficult times before Rachel fixes the foundations the Government just need to prioritise the interests of British citizens welfare above other interests. Next question.
2.4 Pressures on public spending due to recent events
In addition to pressures from inflation and pay, recent events have increased pressures significantly on public spending since SR21, including:
These events have all taken place against a challenging fiscal backdrop, with public debt at its highest level since the early 1960s.[footnote 10]
- Military assistance to Ukraine – The UK has committed £3 billion of military assistance to Ukraine in 2024-25 including £1.5 billion RDEL, in response to its invasion by Russia.
- Asylum – Asylum seeker arrivals, and the costs associated with supporting them in the UK, have exceeded SR21 forecasts. As a result spending on asylum support has increased seven-fold in the last three years, with asylum and immigration resulting in a pressure of £6.4 billion in 2024-25. The Rwanda migration partnership and Illegal Migration Act would have caused these spending pressures to continue rising even faster than before.
- Rail services – Pressures have emerged on rail finances, primarily due to the weaker-than-expected recovery in passenger demand following the COVID-19 pandemic, leading to a pressure of £1.6 billion in 2024-25.
The £6.4bn is the difference between what the Home Office under the Tories guesstimated / planned they would spend on asylum support and what they actually spent. That's why it's part of the 'black hole' - it was the Tory overspend.
