Robin Thicke's controversial chart-topper has been named the most downloaded track in UK music history.
According to a new countdown compiled by the Official Charts Company and unveiled by BBC Radio 1, the track Blurred Lines - which also features vocals from TI and Pharrell Williams - has sold a record-breaking 1.54 million copies since it was released in May.
The best-selling single of 2013, it was banned at several universities and was the subject of campaigns from women's rights groups after some said the lyrics were derogatory and sexist.
The track was accompanied by a video in which Thicke was surrounded by naked dancing models, prompting some to call for age ratings applied to pop tracks.
It overhauls the previous biggest selling download, Adele's Someone Like You, which has now sold 1.53 million copies to date.
