Sir Julian Lewis, Conservative MP for New Forest East, issued this warning over the potential proscription of Palestine Action as a terrorist group.
It comes after activists damaged two RAF Voyager aircraft during a break-in at RAF Brize Norton.
Speaking in the Commons, Sir Julian said: “It would do the country and the Government no favours if they were to lose in court a challenge to the process of proscription, because whereas the secret sabotage of planes would certainly have been an act of terrorism leading to proscription, the fact is, this was a performative act which they announced they had done.”
Palestine Action has claimed responsibility for the incident and shared footage from the Oxfordshire base on its X account, alleging that the planes are used to collect intelligence, refuel fighter jets and transport weapons used in attacks on Gaza.
