The boy band, who finished second behind Alexandra Burke in last year's X Factor, sold over 100,000 copies of their song 'Everybody In Love' to claim the top spot according to the Official Charts Company.

It's the third X Factor affiliated number one in a row with JLS following Alexandra Burke's 'Bad Boys' and Cheryl Cole's 'Fight For This Love'.

With Leona Lewis releasing her new single 'Happy' this week it looks highly likely that X Factor will score a chart quadruple.

Over on the album chart, Cheryl Cole remained at number one for a second week with '3 Words' fending off competition from Bon Jovi's 'The Circle' which entered at two.

Foo Fighters' 'Greatest Hits' entered the album chart at number four.
