Debbie Jevans, Chief Executive of England Rugby 2015, has resigned due to personal reasons.
Jevans said: “This is the right decision for me to make at this time. I am immensely proud of the team and all that we have achieved in the time that I have been Chief Executive.
"Everything is in place to ensure that this is the best Rugby World Cup ever, and I am confident my team will deliver an exceptional tournament. The organisation is strong, there is a great team in place and I am really looking forward to watching the Rugby World Cup as a fan later this year.”
