## Key points

- The second charge is conspiracy to enter a prohibited place under section 4 of the National Security Act 2023, which does not require any foreign involvement to be proven.
- The Attorney General's personal consent is legally required before proceedings for a section 4 offence can be instituted.
- The trial of the accused is due to begin on 25 January 2027 at Woolwich Crown Court.
- AirTanker, a private company, owns the Voyager tankers, not the Ministry of Defence.

Court reports use many of these terms without explaining them. The second charge reflects section 4 of the National Security Act 2023.

## Questions and answers

**What does conspiracy mean in the Brize Norton case?**

Conspiracy means agreeing with others to commit a crime. The prosecution does not have to prove that each person personally caused the damage.

**What is a prohibited place?**

A prohibited place is a protected site such as a military base. The second charge alleges an agreement to enter one for a purpose prejudicial to the safety or interests of the UK.

**What is the 'terrorist connection' in the case?**

It is an allegation the prosecution makes, not a finding. In the Filton case, the same finding added years to the sentences.
