The Women’s World Cup Team Guide on BBC SPORT indicates this fact about Pakistan’s World Cup history.
Pakistan have never played in the World Cup before. Any victory would send them home happy.
However, the official site of the ICC Women’s World Cup 2009 here clearly mentions that Pakistan has participated in the World Cup 1997 hosted in India.
With 11 Teams taking part, including Pakistan and South Africa for the first time, the tournament was structured into two pools for the first time with round-robin matches in each group leading to semi-final qualification for the top two sides.
I’ve complained through the official complaint channel of the BBC. Waiting for the response, if any.
