Absolute disgrace to the uniform. The British Army are renowned for their humour(particularly in adversity) however there is a time and a place.
Outside Buckingham Palace in full view of the general public and tourists is NOT it.
For those who say he was relieving boredom etc remember this.
It is his job to perform Public Duties, it's part and parcel of being a Guardsman I the Household Division, a job he knew full well he would be doing when he VOLUNTEERED to join HM Forces in that particular capacity?
What next? Shall we have them all doing their own little thing as they carry out Public Duties? Shall we not bother with the centuries old Ceremony of the Keys, just bimble along and chuck them to the guard on duty?
His colleagues will take a very dim view of this and I hope he gets the full weight of military law thrown at him, which he undoubtedly will.
The British Army has had drill and tradition at it's very core for over 300 years.
Let's not make a mockery of it. If he doesn't like it he can give his 12 months notice or PVR but either way the Guards in particular and Army in general does not need this type of 'soldier'.
