TWO Green Party politicians brought a case to the Investigatory Powers Tribunal yesterday over claims that they were put under surveillance by GCHQ.

The case has been launched by MP Caroline Lucas, who represents Brighton Pavilion, and London Assembly member Baroness Jones of Moulsecoomb.

Lawyers for the pair allege that their communications are being intercepted as part of the Tempora programme, which monitors and collates all electronic communications data produced in or transiting through Britain and other countries.
