The Duke of Edinburgh did not let the road closures in Windsor change his routine of carriage driving before the first Changing the Guard ceremony in Windsor since new security measures were put in place.

According to Thames Valley Police, there's no specific threat against the ceremony but the changes have been made in the wake of the terrorist attack in Westminster last week.

This is the first time barriers have been placed along the route of the centuries-old tradition at Windsor Castle.

The barriers, designed to stop vehicles, are flanked by police officers - many armed.

At 9am, before the ceremony, police and security officers outnumbered visitors. 

At 10.45am police secured the barriers, effectively sealing the parade route from traffic.

Just before the parade began, the Duke of Edinburgh arrived back at the castle after his morning carriage drive - the 95-year-old certainly not dissuaded from his usual routine. 

Despite the extra security at the ceremony this most British of traditions wasn't hindered in any way.
