Melua ends Leona's reign at no. 1

A duet between Katie Melua and the late Eva Cassidy has ended Leona Lewis' seven-week reign at the top of the singles chart.

The charity track, a cover of Louis Armstrong's 'A Wonderful World', debuted at number one despite only being available from Tesco's. Lewis drops to two with 'Bleeding Love'.

Two Christmas classics grace the top ten this week: 'All I Want For Christmas Is You', at four, and 'Fairytale of New York', which rises four places to eight.
