The headscarf is on sale on the charity's website for £20, where it is described as "a symbol of remembrance that would appeal to British Muslims". The Legion stepped in after the hijab was launched by a pair of smaller charities and sold out. The major servicemen and women’s charity then came on board to cope with the high demand. British Muslim Tabinda-Kauser Ishaq, 25, designed the light blue poppy-patterned headscarf in 2014 while studying at the London College of Fashion. She said: “The idea to do a headscarf came from knowing that many Muslims generally mark Remembrance Day.

“We felt it wasn’t that widely known. The number of Muslim soldiers who fought in World War One was even less known.



"We wanted to create something that illustrated this history.”



During last year's Poppy Appeal, the Islamic Society of Britain and think-tank British Future started selling the hijab for £22.



They produced two runs of the garment, but ended up selling out completing in just a week.



A spokesman for British Future said: "The response we got last year was very positive."



RBL has since slashed the price of the headscarf by £2 in a bid to boost sales.



Ms Ishaq added: "I thought it was a really simple and clean way of saying that I'm very proud of being British and Muslim without it being in anyone's face."



More than 1 million British Muslims wear a poppy to mark Remembrance Sunday and Armistice Day and around 400,000 Muslim soldiers, most from what was then British India, fought for the allies during the First World War.
