Scottish nationalists attempt to sabotage King's Edinburgh Coronation celebration: 'Not my King!'

The King is being presented with the Scottish crown jewels as part of a thanksgiving ceremony to mark his Coronation.

A designated area has been specially cordoned off where campaigners are noisily protesting.

Video footage shows activists from the campaign group Republic chanting "Not My King" during the demonstration.

However, the noise was drowned out by a loud response from supporters of the Royal Family waving Union flags.

The majority of the crowd lining the streets appeared to be attending the event in support of King Charles.

A security operation is underway to control anti-monarchists and ensure the event runs smoothly.

A separate anti-monarchy group are hosting a rally outside Holyrood, which will be attended by Greens co-leaders Patrick Harvie and Lorna Slater.

Assistant Chief Constable Tim Mairs, police lead for the event, said officers will take a "proactive engagement approach" with protesters but that "safety is our priority".

He said: "Campaigning and demonstration is a legitimate, necessary and vital part of life. Abusive, threatening behaviour or activity intended to disrupt the event that risks public safety is not legitimate protest.

"Officers on the ground have to make assessments to quickly consider whether someone's behaviour breaches the threshold of criminality.

"There are a range of factors and circumstances that affect this decision making, as well as any triggers that may lead to wider disruption.

"Every situation is unique. Safety is our priority, balanced against people's rights."

Fifteen roads have been shut down across the city to make way for the thousands of spectators expected to line the streets.
