Former X Factor contestant Marcus Collins has unveiled the video for his new single 'Mercy'.

The track marks the follow-up to his debut single, a cover of White Stripes' 'Seven Nation Army'.

The video sees Collins lead a trek along a street as a bunch of suited up brass players follow.

Some backing singers join in before they all pile into a club and take to the stage, much to the delight of the assembled crowd.

As previously reported, Marcus Collins last month expressed his delight at working with his X Factor mentor Gary Barlow once again.

The Take That star appeared on Collins' debut album as an executive producer and penned a track for the album.
