England captain Charlotte Edwards has insisted that there will not be changes to her side for Sunday's crucial World Cup Super Six match against South Africa.

Having already lost to Sri Lanka and Australia, the defending champions must defeat the Proteas and New Zealand to have any chance of progressing in the tournament.

"I don't like tinkering around with teams, especially with two crucial games coming up," said Edwards.

"I can't see us making any drastic changes. This is the team we feel has the best chance of getting to the World Cup final."

England are on the verge of elimination in India after they were agonisingly beaten by two runs by Australia, despite a last-wicket stand of 31.

Edwards's side will need to improve on a poor batting display if they are to defeat South Africa, a result which could still see them exit the tournament if West Indies win their remaining two games.
