Troubled singer Pete Doherty has checked himself into a rehab centre in Portugal in a desperate bid to get clean. The Babyshambles frontman flew to the clinic earlier this week (begs05JUN06) to try and beat his drug addictions, according to band sources. Unlike the singer's previous failed attempts to clean up, Doherty has organised and funded the trip on his own. He will spend the next few weeks detoxing, after which he will be fitted with "an opiate-suppressing implant". The singer revealed in a recent interview, "For a little while things were too dark to even begin to get my head around. "Spending all my time dropping my trousers to the police. Sat in cells. What I want is a little bit of self-control."
