SPOOKS and undercover cops have admitted making up to 250 blunders while spying on crime and terror suspects, an official report shows.
MI5 officers alone made at least 136 mistakes, called “relevant errors”.
They include ten while conducting “property interference and intrusive surveillance” ops, such as planting bugs in the homes of suspects.
The agency confessed that 23 errors were made while conducting “directed surveillance”.
The MI5 website says this “involves the covert monitoring of someone’s movements, conversations and other activities”.
It adds: “This work is carried out by highly skilled specialist surveillance officers who may work in vehicles, on foot or from fixed observation posts.”
