Appeal organiser the Royal British Legion have turned to pop acts in recent years to raise the fund-raising profile.

Last year Irish heart-throbs Westlife launched the drive for funds and in 1997 the Spice Girls were involved.

Noel Rogers, chairman of fund-raising at the Royal British Legion, said: "Once again it is marvellous to see the Poppy Appeal supported by all generations highlighting the relevance of our annual campaign.

"The Poppy Appeal is the life-blood of the Legion's welfare programme.

"Wearing a poppy, the symbol of remembrance, is a small yet significant gesture when we remember the price of freedom."

The legion is calling on people to observe the two-minute silence on Armistice Day at 1100 on Saturday, 11 November.
