A Sikh Guardsman who was the first to wear a turban during Trooping the Colour is allegedly being investigated for drugs misuse.
Charanpreet Singh Lall was one of three soliders who reportedly failed a random drugs test at Windsor's Victoria Barracks, according to The Sun.
Lall, who is from Leicester, made history in June this year as the first Coldstream Guardsman to take part in Trooping the Colour while wearing a turban.
Now the 22-year-old could be discharged from the Army.
Brigadier Christopher Coles, head of Army personnel services group, said: "I can confirm that a number of soldiers from the Coldstream Guards are under investigation for alleged drugs misuse.
"Drugs abuse is incompatible with military service and those caught taking drugs can expect to be discharged."
