The England squad have been instructed not to use their mobile phones on World Cup matchdays.
This follows the news that Rob Howley has been sent home to Wales with Warren Gatland’s number two now under investigation for an alleged breach of betting and anti-corruption regulations.
The 31 players and all of England’s coaches and backroom staff were given a 20-minute presentation, which highlighted the plight of Phil Blake, the former Leicester defence coach who was given a six-month ban in 2014 for breaching the RFU’s betting rules.
They were also advised to stay off their phones from an hour before kick-off at stadiums on matchdays due to fears they could be targeted for information.
It is understood that there were six reported incidents of players or staff being suspiciously approached at the 2015 World Cup.
