Grime collective Roll Deep are celebrating their second week at the top of the singles chart while Diana Vickers has grabbed top place in the album charts at the first attempt.
The former X Factor contestant saw her album Songs From The Tainted Cherry Tree go straight in at number one.
It follows the success of her debut single, Once, which went straight to the top of the charts when it was released last month.
Roll Deep fought off the challenge of Usher featuring Will.I.Am to hold on to the top of the singles chart with their song Good Times featuring guest vocalist Jodie Connor.
The long-standing east London group, who became one of the figureheads of the grime scene in 2005, count Dizzee Rascal and Tinchy Stryder among their former members.
There were two new entries in the singles top 10 with Australian drum 'n' bass crew Pendulum going straight in at number four with Watercolour and MC Aggro Santos at number five with Candy featuring Kimberly Watts.
There was just one other new entry in the album charts with American country music group Lady Antebellum's Need You Now going straight in at number eight.
