United Kingdom in the Eurovision Song Contest 1999

The United Kingdom was represented at the Eurovision Song Contest 1999 with the song "Say It Again", written by Paul Varney, and performed by the group Precious. The British participating broadcaster, the British Broadcasting Corporation (BBC), organised a public selection process to determine its entry for the contest, The Great British Song Contest 1999. Eight songs competed over two rounds, with four songs selected through a radio-broadcast semi-final to advance to the televised final round, held on 7 March 1999, where viewers selected the winning entry through televoting. "Say It Again" performed by girl group Precious received the most votes and was selected to represent the nation in the contest.

Precious performed fifth at the international contest, and at the close of the voting process the UK finished in 12th place, receiving 38 points from 10 countries. At the time this result was the UK's second-worst placing in its competitive history, and was the nation's first finish outside of the top 10 countries in 12 years. "Say It Again" charted in several singles charts in Europe following the contest, and following further limited commercial success as a group Precious subsequently disbanded in 2001.
