Tinchy, N-Dubz make it three weeks at No.1

Tinchy Stryder and N-Dubz have extended their reign over the UK singles chart to three weeks.

'Number One', their aptly-titled collaboration, presides over a top five that is entirely unchanged from last week's.

La Roux remain at two with 'In For The Kill', while Ironik holds steady at three with 'Tiny Dancer (Hold Me Closer)'.

The only track in the top ten to climb to a new peak is Lily Allen's 'Not Fair', which advances from nine to eight.

Meanwhile, Miley Cyrus posts two tracks in the top 20, rising from 13 to eleven with 'The Climb' and 30 to 18 with 'Hoedown Throwdown'.

Other notable gains come from Britney Spears, who jumps from 23 to 20 with 'If U Seek Amy', and Alesha Dixon, who vaults from 37 to 25 with 'Let's Get Excited'.
