It comes at a time when the off-field behaviour of England's players remains in the spotlight following the arrest of batsman Ben Stokes following a brawl outside a Bristol nightclub in September.

The England and Wales Cricket Board is investigating reports English batsman Jonny Bairstow headbutted Australian batsman Cameron Bancroft in Perth earlier this month.
Cameron Bancroft was allegedly attacked by Jonny Bairstow at a Perth pub weeks ago.
The incident allegedly took place at the Avenue Hotel in Perth, before Bancroft was seriously in the frame for a Test call-up, while England was in town for its tour-opening tour match against a Western Australian XI.
It's understood Bancroft only told teammates of the incident in the past few days and has accepted an apology from Bairstow.
European Central Bank on Sunday released a statement after discussions with their wicketkeeper-batsman in which they came close to exonerating Bairstow while adding that they will conclude their investigations after the first Test.
Seamer Mitchell Starc, meanwhile, has confirmed that Australia would continue to target the fragility of England's tail as his side moved to the brink of a 1-0 lead in the five-match series on Sunday. There has been no report of any incident from the venue, security or police and there was no injury reported.
"They say Bairstow and Bancroft knocked heads while grappling rugby-style in a non-aggressive manner".
But he was one of three England players fined by the European Central Bank in the wake of a night out in Bristol that saw Ben Stokes arrested for alleged assault.
The players compiled a code of conduct at the start of this tour in an attempt to avoid any repeat of the Bristol incident that has cast such a cloud on this tour but at the same time management were determined to carry on treating the players as adults. We certainly don't want to keep players in their rooms because it is a long tour.
