Eddie Jones is under huge pressure at England but there is no obvious candidate to replace him at Twickenham.
The Aussie, who departs his role no matter what after the 2023 Rugby World Cup, remains under serious pressure following another very poor Six Nations.
'We've got an advanced succession plan in place,' Bill Sweeney said. 'We've got a war room that's got every English coach you can imagine - based here and based internationally. It's got contracts and all sorts of things. There's a very definite plan.
'We believe we've got such a wealth of English coaches in the game. As a leading rugby nation, we should be developing English coaches and an English style of play. That should be long-term and therefore the preference would be to have an English set-up as far as I'm concerned.'
'Warren Gatland hasn't been approached because we believe that Eddie's the person to take us through to 2023,' Sweeney added.
