Internal Counter-Intelligence Service

The Internal Counter-Intelligence Service was a military/intelligence organisation operating within the United Kingdom, with a remit to combat alien and paranormal incursion on UK soil. It was shut down following involvement in ethnic cleansing and an attempted coup.

History
The ultra-nationalist group ICIS had been around for a few years by the early 21st century, possessing ties to The Forge. (Project Valhalla) ICIS and its government backers like press secretary Philip Kirby were becoming increasingly concerned with the country's involvement in the United Nations and European Union, which they thought was undermining its sovereignty to a dangerous level. (BFA: The Longest Night) They recruited a young nationalist soldier named Brimmicombe-Wood soon after his training, grooming him to become a double-agent within UNIT. (BFA: The Wasting)

By around the mid-21st century, the government had decided to shut down the UK branch of UNIT and replace it entirely with ICIS. By this point, Brimmicombe-Wood was in command of UNIT. Both groups began using UNIT's base in preparation for the change. Before the handover, ICIS fired on a Silurian diplomatic party, resulting in a retaliatory strike at London that both ICIS and UNIT dealt with; Brimmicombe-Wood commanded both teams, and ICIS were deliberately instructed to leave no prisoners. To keep this out of the press, ICIS's Sergeant French captured and tortured BBC journalist Francis Currie into staying quiet.

This backfired when, on the day of the handover and resulting press conference, a Silurian ambassador made contact with Alastair Gordon Lethbridge-Stewart, while UNIT's Emily Chaudry became aware of French's actions. They deliberately revealed the Silurian's and UNIT's remit at the press conference, causing ICIS' Captain Andrea Winnington to fire on the reptilian ambassador. ICIS was discredited and UNIT was able to argue that it should maintain control of alien matters. Both Winnington and French were arrested, ICIS was given a separate base with a UK security remit separate from UNIT's, and both groups co-existed. (BFA: The Coup)

ICIS were already working to eventually take over the country to protect its sovereignty. They used reverse-engineered alien technology and government helplines to program the general public into becoming sleeper agents, intending to use them to trigger a wave of terrorism and violence. (BFA: The Longest Night)

They were also using alien spacecraft blueprints stolen from UNIT to construct a time-space teleportation device, and to further this they raided a UNIT convoy to steal the spacecraft it was transporting. In the process, Brimmicombe-Wood was "abducted". However, their continued time-space experiments accidentally caused time fluctuations, leading to a series of horrific accidents. ICIS destroyed the site of the experiments, ensuring nothing led back to them. (BFA: Time Heals) Unknowingly, they also released an alien virus from the spacecraft, which soon began spreading across Earth. (BFA: The Wasting)

When the Prime Minister signed the controversial Euro Combine treaty, ICIS finally triggered their coup. They activated random sleeper agents to create a wave of destabilising terrorism nationwide, turning the country against each other - riots and ethnic violence became endemic. The Deputy Prime Minister was also triggered into killing herself, leaving the PM vulnerable while Philip Kirby pushed him to send ICIS onto the streets. To discredit UNIT, Winnington was freed from jail and sent to provoke Chaudhry into murdering her while UNIT's new commander Timothy Dalton was 'triggered' to assassinate the Prime Minister after ICIS was deployed.

Chaudhry was able to prevent this, revealing the conspiracy to the PM and leading to him declaring ICIS would be shut down. The defeated Winnington was left demoralised after seeing the carnage caused in London by her faction; Kirby, howevered, triggered a suicide bomb in a final act of defiance, devastating 10 Downing Street and killing Dalton. (BFA: The Longest Night)

ICIS still remained in operation after this, and was called in to assist during the growing alien plague. Knowing UNIT would be against them, they swiftly framed them for deliberate murders and secured orders to arrest the UK contingent's officers. Chaudhry and Lethbridge-Stewart led as many loyal UNIT soldiers as possible into going on the run, and in the process discovered Brimmicombe-Wood had been leading ICIS all along. ICIS pursued UNIT to Russian soil, attacking to wipe them out (despite UNIT trying to deploy a cure for the plague). Brimmicombe-Wood was defeated in combat and arrested, while ICIS' newer crimes were revealed.

The organisation was finally shut down. (BFA: The Wasting)
