A viral social media post claiming that London's black cab drivers are covert MI5 agents has recently gained traction, alleging the British government trained 3,000 drivers to catch criminals and stop money laundering. This in-depth look at the claims reveals that the widely circulated story is a conspiracy theory with no credible evidence.
The claims suggest that these drivers use a secret app to transmit audio to intelligence services. However, official sources and established news organizations have not reported any such program. The apps used by black cab drivers, such as Gett, Freenow, and Taxiapp, are for standard ride-hailing services. Their privacy policies do not indicate any functionality for transmitting passenger audio to external parties or government agencies.
While the idea of black cab drivers as spies is a compelling narrative, the reality is far less sensational. The only known connection between the London taxi trade and British intelligence services is logistical. The "Knowledge," the famously difficult test that cabbies must pass to operate a black cab, provides them with an unparalleled understanding of the city's streets. This has led MI6 to previously advertise for former cab drivers to fill chauffeur and logistics roles, utilizing their expertise in navigation for official purposes. There is no evidence they are being used as listening devices or undercover agents.
The theory also appears to draw inspiration from declassified MI5 documents that reveal how the agency's surveillance officers, known as "watchers," were advised on how to use taxis during the Second World War. These documents detail how watchers could instruct a cab driver to "follow that cab" and were advised to "co-opt his help" by offering a generous tip and a plausible cover story. This historical use of taxis as a tool for MI5 surveillance is fundamentally different from the modern claim of cab drivers being agents themselves.
In conclusion, the claim of black cab drivers working as secret agents for MI5 is an unfounded conspiracy theory. While the unique skills of London's cabbies have been appreciated by intelligence services for their logistical value, there is no public or credible information to support the idea of a widespread, government-run surveillance program.
Cracking London's Legendary Taxi Test is relevant as it provides a look into the extensive training and "Knowledge" that London black cab drivers undergo, a key element often misconstrued in the conspiracy theory.
