England head coach Eddie Jones has signed a contract extension to keep him in the role until 2021, the Rugby Football Union (RFU) said on Wednesday.
Former Wallabies coach Jones, who took over the reins at England in November 2015, was originally contracted until the end of the 2019 World Cup campaign in Japan.
The 57-year-old has led England to consecutive Six Nations triumphs and series wins in Australia and Argentina.
"These are exciting times for English rugby, with a focused and committed squad who are full of potential and determined to win," Jones said.
"I will continue to work as hard as I can to make England the world's best rugby team."
RFU chief executive Steve Brown said: "Eddie's results as England head coach speak for themselves.
"Under Eddie's leadership, we have risen from eight to second in the world - and Eddie won't be satisfied until we are number one.
"He has a 95 per cent win rate at the helm, and has been a galvanising force for the RFU, bringing focus, clarity and extraordinary commitment to the role."
