England have successfully dethroned Australia from the pole position in the ICC Women's Rankings following the annual update.
Heather Knight's side had a successful outing during the home Women's World Cup 2017 where they defeated India in the finals to clinch the trophy.
England are now level with Australia with 128 points but find themselves ahead in decimal points as the rankings now take 100 percentage weightage for the 2016/17 season while 2014/15 and 2015/16 seasons now have 50 percentage weightage.
India, who were the other finalist in the recently concluded World Cup have gained three rating points and now have a 15 point lead over fifth-placed West Indies.
The remaining eight teams have retained their position in the table.
England skipper Knight insisted that the team is not a finished article yet and is looking to carry forward the momentum into the Ashes series.
"It's flattering to be named as the No.1 side in the world because it's a sign of how much progress we've made.
"It won't take anything away from the challenges ahead of us, though. We're a developing side and our journey isn't finished yet.
"We have plenty more hard work to do, starting with the Ashes in Australia this winter but it has been a great 12 months for us.
"We'll never forget the feeling of winning the ICC Women's World Cup on home soil and we want to keep pushing forward as a side so we can experience more moments like that."
