Westlife sold over 50 million records worldwide, a total that included studio albums, singles, video releases, and compilation albums. The group accumulated 14 number-one singles in the United Kingdom (the third-highest in UK history), tying with Cliff Richard and ranking just behind The Beatles and Elvis Presley.
