THE GREEN Party raised questions over police accountability yesterday after reports emerged that secret files kept on peer Jenny Jones were destroyed in a cover-up of spying operations on political activists.

Baroness Jones of Moulsecoomb, who is also a member of the London Assembly, discovered two years ago that she had been placed on the Metropolitan Police database of “domestic extremists.”

Files obtained through data laws revealed that records were kept of her movements between 2001 and 2012 — even as she sat on the committee that scrutinises Met operations.
