Matt Cardle has secured a third week at the top of the UK singles chart with his debut track 'When We Collide'.
The X Factor champion's tune became the first chart-topper of 2011 - having already won the titles of last year's Christmas number one and the last number one of 2010 - after holding Rihanna and Drake's 'What's My Name' into second place for a third consecutive week.
The only other new face in this week's top five is Katy Perry's 'Firework', which rises from eight to five, while Olly Murs returns to the top ten after temporarily dropping to 12 last week.
The stability at the top of the chart is not replicated between positions 11 to 20, which are populated by a significant plummeter in the shape of Katy B's 'Lights On', down seven after arriving at four last week, and a total of six climbers.
The most notable of these are Mike Posner's 'Cooler Than Me', Jessie J's 'Do It Like A Dude' and The Wanted's 'Lose My Mind', which after settling for spots in the bottom half of the top 40 last week advance seven, three and ten places respectively to 17, 18 and 19.
