Lady Gaga's single 'Poker Face' and Susan Boyle's debut album I Dreamed A Dream have been crowned Britain's biggest-selling records of 2009.
Boyle, the runner up on the reality TV show Britain's Got Talent, claimed top spot in the year's album chart after her album sold more than 1.5 million copies in six weeks.
The 48-year-old Scottish singer was unknown before her appearance on the talent show last April.
Lady Gaga's album The Fame was in second place in the album sales charts, with Michael Buble's Crazy Love third.
