Dubstep duo Nero have found themselves in a very close battle for the UK's No.1 single this week. 

The pair released their latest offering, 'Promises', on Sunday, August 7 and according to the Official Charts Company it is currently 550 sales ahead of the chart-topping 'She Makes Me Wanna' from JLS. 

Cher Lloyd's debut single, 'Swagger Jagger', has already dropped to No.3 although it has only fallen behind slightly so it will be a race for the top spot on Sunday, August 14 when the positions are confirmed. 

The midweek chart update will be unveiled tomorrow (August 10), but until then you can check out Skrillex's blistering remix of Nero's 'Promises' here:
