Seeing that the Irish Guards are providing No. 5 Guard this year in Trooping the Colour, I believe that man is the tailor. The Lance Sergeant at 8:17 is holding a clipboard and is walking with the tailor. You can see that they are checking the guards tunics for any adjustments that may need to be made.

It’s a very thorough inspection.

The Master Tailor.

Most probably the master stitch.

It is the manager from Marks & Spencer..............that's where they got the new tunic................

He is the Head Tailor. They're checking the New Uniforms for proper sizing.

A'int got a clue mush. Ooo is ee?

Dunno 😊

The Irish guards 💂🇬🇧🍀

If the gentlemen is the😢 regimental tailor would he have undertaken an inspection of uniforms prior to the assembly ?. The Lance Sergeant is surely noting down the comments of the officer inspecting the troops as happens for all guard mounting duties irrespective of which regiement providing the guard.

Rupert .......

Certainly an Officer of the Regiment.

The tailor?

Mr Bean?

If you don't know then go away and learn. There's too many of these channels making money off our troops on duty without any knowledge of the troops.....that's disrespectful!
