Singer Amy Winehouse has been found dead at her flat.

The 27-year-old was discovered at the property in north London by emergency services at around 3.54pm on Saturday afternoon, according to sources.

It is understood her death is being treated as "unexplained".

The Back To Black artist cancelled all tour dates and engagements last month after a series of erratic public appearances.

She had been troubled by drink and drugs problems throughout her career.

The London Ambulance Service attended her flat but were unable to save her life, sources said.
