A two minute song which features nothing but silence is on course to debut inside the top-20 on the UK singles chart this weekend.

The track, which is already performing strongly on the iTunes chart, has released by the British Legion's Poppy Appeal.

It includes a video that features Radiohead's Thom Yorke, Plan B, The Saturdays and prime minister David Cameron.

All proceeds from the sales of 'Two Minute Silence' will go towards helping members of the armed forces and their families.

Current number one Rihanna is expected to retain her position at the top of the singles chart with 'Only Girl (In The World)', according to the Official Charts Company.

Meanwhile, in the album chart, Susan Boyle is on course to top the countdown with her second effort 'The Gift'.
