Bruno Mars has scored the U.K.'s fastest-selling solo album of the year (12) so far with his new release Unorthodox Jukebox.

The pop star's latest work debuted at number one with sales of 136,000, replacing British singer Olly Murs at the top of the countdown.

His Right Place Right Time slipped to two, while Michael Buble was at three with his festive project Christmas.

Meanwhile, another chart record was set in the singles chart - James Arthur, this year's (12) winner of the British version of The X Factor, landed the U.K.'s fastest-selling single of the year after shooting to number one with his new song Impossible.

The singer, who was crowned the champion on the reality Tv show earlier this month (Dec12), managed to shift 490,000 copies of the track, easily smashing the previous record of 152,000 held by Cheryl Cole for her Call My Name tune, which was released in June (12).

Arthur's feat keeps rapper and Britney Spears from taking the top spot - their Scream & Shout collaboration entered at two, while Bruno Mars took third place with Locked Out of Heaven.
