Steve Borthwick has been appointed as England head coach on a five-year contract.
Borthwick, 43, masterminded Leicester's Gallagher Premiership title triumph last season, and he succeeds Eddie Jones in English rugby's top job.
Jones was sacked almost two weeks ago after presiding over England's worst year of results since 2008, managing only five wins from 12 games.
The Rugby Football Union also announced that Leicester assistant coach and former Leeds Rhinos captain Kevin Sinfield will join Borthwick as defence coach at Twickenham.
"I'm deeply honoured to be appointed England head coach and I am very excited by the challenge," Borthwick said.
"The English game is full of talent and I want to build a winning team which makes the most of our huge potential and inspires young people to fall in love with rugby union the way I did."
RFU chief executive Bill Sweeney insisted Borthwick was their "lead choice and preferred candidate" to replace Jones from the outset.
He told a press conference: "Steve has been involved in two World Cup cycles, coaching Japan from 2012 to 2015 with Eddie Jones.
"And appropriate to put on record our thanks to Eddie for the seven years he had here. Steve was also in the coaching set up from 2015 to 2020, which included the World Cup final in 2019.
"He was also coach of the 2017 Lions tour that had the draw in New Zealand, so his credentials are impeccable.
"We have had a very rigorous coaching plan in place headed up by Nigel Redman. We had discussions post-2023 and Steve was always our lead choice and preferred candidate to come in and do the England job so absolutely delighted he is here today."
