One Direction are on course to nab the number one single this weekend with their Comic Relief single storming ahead of rivals.
The group have recorded a version of Blondie track One Way Or Another, which featured on hit album Parallel Lines, with the song segueing into Undertones single Teenage Kicks.
The Official Charts Company said the release was outselling its nearest rival by two to one, based on pre-orders and Monday sales.

If they can hold off competition from Bauuer's Harlem Shake and Macklemore And Ryan Lewis's Thrift Shop, it would give them their third chart-topping single.
Official Charts Company managing director Martin Talbot said: "If anyone can keep the likes of Harlem Shake from the top spot, One Direction can."
The number one single will be announced on Sunday evening.
