An investigation into allegations of player misconduct during England's tour to New Zealand will be launched today.
The Rugby Football Union's disciplinary officer Jeff Blackett will conduct the probe into a night that ended with allegations of serious sexual assault against four players.
No formal complaint has been made to the police and the quartet, who were named by a national newspaper on Tuesday, have denied any wrongdoing in the strongest possible terms.
Blackett will complete his investigation as quickly as possible but plans to interview every member of the squad, a process that could take weeks.
The probe will run separately to the police investigations taking place in New Zealand.
An RFU statement read: "The management board are concerned at the damage to the game's reputation as a result of the allegations made regarding the behaviour of four of the 32-strong touring party after the first Test match.
"The board noted that no formal complaint had yet been made to the Auckland police, that the players deny the allegations and that they have the full support of the England squad and team management in this respect.
"The board agreed that England players have always been great ambassadors for the game and their country.
"Wearing the white shirt is a great honour that brings with it great rewards but also carries great responsibilities.
"In the age of celebrity, England players must always be aware of their position and the dangers that may exist for them at all times."
Elite rugby director Rob Andrew yesterday presented the RFU's management board with his report into the tour.
After missing out on England's 2015 RBS 6 Nations campaign through injury, centre Brad Barritt admits he is determined to make up for that disappointment in style with club side Saracens during the season run-in.
