Every four years the Muslim Women's Games are held in Tehran.
The International Olympic Committee has expressed its support for this strictly female tournament at which, according to Islamic rules, no men may spectate and no photography is permitted.
The organisational staff is entirely female from ex-President Rafsanjanis daughter at the head of the enterprise, down to the referees and security guards.
However, women's rights groups have denounced it as an Iranian propaganda ploy.
As the debate continues, 13 young Muslim footballers from around Britain prepare to represent their country at the games.
