Good Times as Roll Deep top chart
Grime collective Roll Deep have emerged triumphant in a neck and neck battle with US R&B giant Usher for the number one single in the official chart.
The long-standing east London group took the top spot with new single Good Times, featuring guest vocalist Jodie Connor.
Good Times had been fighting head to head with Usher's former number one single OMG, featuring Will.I.Am, to hold on to the number one slot since last Wednesday's official chart update - when less than 2% of sales separated the contenders.
Roll Deep became one of the figureheads of the nascent grime scene in 2005 when they released their debut album In At The Deep End as well as two singles, The Avenue which peaked at number eleven in July 2005, and Shake A Leg which peaked at number 24 later that year.
Roll Deep's alumni include number one artists Dizzee Rascal and Tinchy Stryder. The current line-up includes founder members Wiley, Breeze, Scratchy, Flow Dan and Danny Weed, as well as crew veterans Brazen, Manga, J2K and Target.
In the Official Albums Chart, Usher was denied again as Plan B - also known as east London native Ben Drew - reclaimed number one with second album The Defamation Of Strickland Banks.
The record debuted at number one two weeks ago before briefly relinquishing the top spot to AC/DC's soundtrack to feature film Iron Man 2 last week.
Usher's new album Raymond V Raymond, which had been selling 20% more than Strickland Banks earlier in the week and was number one on Wednesday's official chart update, had to settle for entering at number two in the final countdown.
The only other new entry in the Official Singles Chart Top 10 is Taio Cruz's Dirty Picture featuring Kesha at number ten, up two places from last week's number twelve.
There are three other new entries in this week's official albums chart top 10: TV's Glee cast's Glee Cast, The Music, The Power Of Madonna straight in at number four, Welsh rock/metal band Bullet For My Valentine's Fever straight in at number five and Cornish sea shanty group Port Isaac's Fisherman's Friends' album of the same name is straight in at number nine.
