Emergency Protocols

The Emergency Protocols detailed the actions the British government was to take in the event of an alien incursion. They listed people who could help in such a crisis, notably the Doctor and members of UNIT.

Under the jurisdiction of the Emergency Protocols, military officials could authorise immediate executions. When the protocols were activated, computer software began searching all communications for key words.

When a Slitheen craft landed in the River Thames and the Prime Minister went missing, the Emergency Protocols were handed to Joseph Green or more precisely, the Slitheen posing as him.

Jackie Tyler phoned the BBC's alien helpline and told them about the Doctor. The computer software detected this and the word "TARDIS", initiating a Code Nine.

While hiding in the cabinet room of 10 Downing Street, Harriet Jones browsed the protocols for any information that could help them defeat the Slitheen. Most of the people it listed were already dead. (DW: Aliens of London/World War Three)
