British spies are expected to take the stand against accused al-Qaeda plotter Abid Naseer in Brooklyn federal court Tuesday — but they will be in disguise and courtroom sketch artists will leave their faces blank.

Prosecutors lobbied to bar the artists from depicting the MI5 agents.

But Judge Raymond Dearie ruled that the artists instead will leave “blank faces.”

Naseer is charged with being a member of a global ring that plotted attacks on the New York subway, Manchester, England, and Denmark.
