Troubled singer Pete Doherty has unveiled the new video to his charity single in aid of the Amy Winehouse Foundation.

The Libertines frontman is donating profits from his track, Flags of the Old Regime, to the charity which aims to tackle drug and alcohol misuse among young people.

Amy, who became an international star with her Back to Black album, died of alcohol poisoning four years ago at the age of 27, while Pete, 35, has had a string of high-profile battles with drug addiction.

The pair were close friends before her death and the single was written by Pete to pay tribute to the Rehab singer, his spokesman said.

The black-and-white video was filmed at Karma Sound Studios in Thailand, where Pete has recently had a stint in rehab.

Flags Of The Old Regime, which is available on vinyl and as a digital download, is released on March 9.
