It’s interesting to see the Mounties there.
They have done a good job for all of it considering the minefields they had to navigate with the issues surrounding Prince harry and Prince Andrew. Prince Harry was so put out over the ER being taken off his uniform but not Andrew that he even considered not wearing the uniform for the vigil.
Media still going on about how Prince Harry was invited then disinvited to that reception. I suspect he was never really invited.
The guess is that the Queen herself wanted them in that position leading the procession. The RCMP gifted the Queen her favourite horse Burisma which she used for many years in trooping of the colour ceremonies and no doubt rode on many other occasions.
There are troops from every Commonwealth Realm in the procession, but the Royal Canadian Mounted Police have certainly been given a very prominent position.
