Columbian Intelligence head resigns

The head of Colombia\'s intelligence services has resigned after admitting her agents spied on left-wing political opponents of President Alvaro Uribe.



Maria del Pilar Hurtado says she is stepping down to preserve the honour of the security services, known as Das.



Two days ago, an opposition senator, Gustavo Petro, accused them of monitoring his movements.



He said that members of his Democratic Pole party had also been under surveillance.



Ms Hurtado says neither she nor President Uribe had ordered the surveillance.
