Well the list has been updated and the new number is Katie Melua who has finally knocked off Leona Lewis off the top of the singles charts, ended Bleeding Love’s 7 week reign.
Eva Cassidy who died of cancer in 1996 had a duet with the folk singer which is a haunting version of What A Wonderful World.
It is 23-year-old Katie's first No 1. And her achievement is even more remarkable because the single has only been available from Tesco. All proceeds go to the British Red Cross.
'The people of Britain have once again shown how generous they are when it comes to helping other people,' Katie tells the Daily Mirror.
