England head coach Eddie Jones has signed a new contract which sees him remain with the national team until 2021.
The RFU has announced its plans to appoint a new head coach at the end of the 2019/2020 season to work with Jones for a year and then lead England into the 2023 World Cup.
The Australian, who assumed the role from Stuart Lancaster in 2015, had previously voiced his intention to leave his post following the conclusion of the 2019 World Cup in Japan but will now stay until August 2021.
"Coaching England is a dream job for me, and I was delighted to be asked to stay on after Rugby World Cup 2019," he said in a statement.
"I have been completely focused on developing a team capable of being the number one rugby team in the world and winning the World Cup in 2019. I never take my role as England head coach for granted and did not presume I would be asked to stay on, but, once the conversations started very recently, it was not a difficult decision to make.
"These are exciting times for English Rugby, with a focused and committed squad who are full of potential and determined to win. I will continue to work as hard as I can to make England the world's best rugby team."
The RFU also confirmed the 57-year-old's new contract holds a performance-based break clause, based on England's performance at next year's tournament.
Under Jones' guidance, England have sealed back-to-back Six Nations championships and have emerged as the All Blacks' closest challengers to the accolade of "world's best".
RFU CEO Steve Brown added: "Eddie's results as England head coach speak for themselves.
"Under Eddie's leadership, we have risen from eighth to second in the world -- and Eddie won't be satisfied until we are number one.
"He has a 95 percent win rate at the helm, and has been a galvanising force for the RFU, bringing focus, clarity and extraordinary commitment to the role.
"We now have a robust succession planning process in place which will avoid the historically disruptive pattern of resetting the coaching team and performance system every four years. Eddie will be a big part of this process, and wants to ensure a smooth handover to his successor."
Jones, who is due to announce his squad for the 2018 Six Nations campaign on Thursday, will face the media at 2pm.
