MI6

The Secret Intelligence Service, or MI6, is Britain's primary intelligence agency (along with MI5). The organization is tasked mainly with the covert overseas collection and analysis of human intelligence in support of the United Kingdom's national security. MI6 operatives are known for espionage, counter-espionage, and counter-terrorism.

MI6 has an expense account at the airport to fund flights for their agents, apparently it being common for British spies to head to Mexico and the Caribbean. Some operatives can fly themselves to their locations. They have a secret intelligence facility in the Tower Bridge that has computer access. Many spies do not know about this. It may be decommissioned, but Claire Hutchins knows about it.

MI6 has also been monitoring elusive coder Orion for years, but to no avail, as they have never seen him exit his mansion, and do not know what he looks like. They suspect he has a secret exit, however there is no proof of this.

Junior Agent Academy
Similar to the CIA, the MI6 also has a junior agent academy, but nothing about it is mentioned in the series other than its existence. MI6 agents-in-training lack an outdoor facility, so they are sent to the CIA Academy's Wilderness Survival Training facility as exchange students every summer. MI6 also does exchange student programs, as seen with Hank Schacter. Students are known for their cutting edge forensic technics. Many students can parachute in the start of their second year. They also teach students how to do a car chase on the other side of the road. Chemical warfare is also a major part of their curriculum.
