Pete Doherty has opened up to Louis Theroux about the death of Mark Blanco back in 2006, and said he “understands” the anger his mother feels towards him.The discussion arose as the Libertines and Babyshambles singer took part in a new series hosted by Theroux, titled Louis Theroux Interviews, which took a close look at the life and career of the musician.In one part of the interview, the focus was turned to the death of amateur actor Mark Blanco, who died while attending a party that Doherty was also at.Held at the east London flat of Paul Roundhill, the incident occurred in 2006 when the actor fell from the first-story balcony and died of a sustained head injury. Doherty has always denied any knowledge of how Blanco came to lie dying on the pavement after going over the stairwell balcony.
