Norwegian duo Nico and Vinz have held onto their number one spot.

The singer-songwriting pair's single Am I Wrong topped the Official Singles Chart for the second week running.

Last week the pair - both former substitute teachers - became the first entirely Norwegian act in nearly 30 years to appear at pop's summit.

There was no change to the top three, with Rude by Canadian band Magic! staying at two and Love Runs Out by OneRepublic also static at three.

Canadian singer-songwriter Kiesza was the highest new entry, with Giant In My Heart debuting at four, while Ella Henderson's Ghost completed the top five.

Meanwhile Ed Sheeran's X remained on top of the albums chart for the eighth week in a row.

It is the longest-running number one since Adele's 21 spent 11 weeks at the chart's summit after its release in January 2011.

Sam Smith climbed one place to two with In The Lonely Hour, while Dolly Parton's Blue Smoke dropped to three.
