The Rugby Football Union (RFU) have confirmed Mike Catt has joined Stuart Lancaster's staff as England's new attacking skills coach.
The 40-year-old, who was capped 75 times by England and was selected for the 2001 British & Irish Lions tour of Australia, impressed during a temporary spell within the national set-up on the recent tour of South Africa.
Despite Andy Farrell's return to the international scene, Catt has now been handed a permanent position as England prepare to face Fiji, Australia, South Africa and New Zealand in the autumn.
Lancaster said: "Mike made a big impression in South Africa, both on the players and the management.
"When we got back I asked him to outline his vision for developing not only the skills of the senior team, especially in attack, but with our younger players in the Saxons.
"Having played at the highest level for many years and developed his coaching during his time at London Irish he has a clear plan for developing these skills."
Catt left London Irish with two years remaining on his contract and Lancaster has thanked the Aviva Premiership club for allowing him to leave straight away.
"I'd like to thank London Irish for reaching a compromise with us and allowing Mike to start immediately," he continued.
"We have always been an integrated coaching team covering all areas of the game and Mike will be a great addition alongside Graham and Andy.
"We have a massive challenge ahead of us with the QBE internationals in November but beyond that we need to ensure we have the highest standards across all our representative teams and programmes and Mike will help deliver those."
