Britain's Got Talent judge Alesha starred on the BBC One show in 2007 - which she went on to win - has given her views on the latest controversies.
"From my experience and my knowledge there is no fixing on Strictly and there never has been," Alesha told The Mirror. "It's a brilliant show and the public decide who wins and I think you always get these little hiccups where accusations are made, but there is really nothing dodgy about that show."
Alesha also said that it's the "cleanest show on television".
Strictly has hit headlines in recent weeks following claims from professional dancer Ola Jordan that judges "over-marked and under-marked" to save popular contestants.
Most recently, Jamelia suggested that show bosses fixed it for Peter Andre to stay after claiming producers "re-recorded" the crowd reaction to his dance.
A BBC spokesperson said "continuity shots were taken during a break in filming to reset the dance floor" and judge Len Goodman also denied Jamelia's claims.
