The album, which includes singles Rehab and Tears Dry On Their Own has achieved five platinum sales awards.

Presently, the second and third best selling albums of the year are Leona Lewis's Spirit and Mika's Life in Cartoon Motion.

According to the BPI, Lewis sold 1.27m copies of her album in just five weeks, becoming the fastest-selling debut in UK history.

"Amy Winehouse's Back To Black is in pole position to be the year's biggest seller," BBC quoted Matt Phillips, spokesman for record labels body the BPI, as saying.

"But more than 6 million albums were sold last week, and as this weekend is likely to be the biggest of the year for music sales, Leona may close the gap," he added.

Mika's debut album, which released in February, has just passed the one million sales mark.
