SPECULATION is mounting that blacklist campaigners are being spied on by police after the Metropolitan Police yesterday refused to confirm or deny accusations against undercover units including special branch.

In response to a Freedom of Information Act request by investigative journalist Phil Chamberlain the Met quoted Section 24(2) of the Act claiming that it was in the “public interest” for them to refuse to “confirm or deny in order to safeguard national security.” 

The Met has been embroiled in a number of scandals in recent years over the use of undercover officers to infiltrate campaign groups.
