Controversial former X Factor finalist Cher Lloyd looks set to score a number one single at the first time of asking this Sunday with Swagger Jagger, while Amy Winehouse’s Back To Black should spend another week at the top of the albums chart.

Swagger Jagger (Syco), which divided critical opinion when a demo version leaked earlier this year, has already sold more than 30,000 units this week, putting it far ahead of its nearest competitor, current number one JLS feat Dev’s She Makes Me Wanna (Epic).
