Eddie Jones has extended his contract with England until August 2021 - and will help train up his successor.

The Rugby Football Union moved quickly to keep hold of a coach who has turned around England’s fortunes following the 2015 World Cup flop.

Despite having almost two years left on his current deal, the RFU Board decided that 22 wins in 23 Tests was sufficient reason to offer the Australian a contract extension.

Jones said: “Coaching England is a dream job for me, and I was delighted to be asked to stay on after Rugby World Cup 2019.

“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.”

A performance-based break clause has been put in place in case England make as much of a pig’s ear of next year’s World Cup as they did the last one.

There is also a ‘succession process’ for appointing Jones’ successor, likely to involve appointing a new head coach by the end of the 2019/2020 season.

The next-in-line will work with Jones until the summer of 2021, before leading the team into 2023 World Cup.

RFU boss 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% 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 names his Six Nations squad tomorrow ahead of England’s opener against Italy in Rome on February 4.
