King's coronation: No political pressure to crack down on protestors says police chief

The force faced fierce criticism of arrests made around the event, including volunteers who handed out rape alarms and six members of the campaign group Republic that had liaised with police for weeks before the coronation to organise their own protest.

A complaint has also been lodged by royal fan Alice Chambers, 36, was held in custody for 13 hours after being mistaken for a Just Stop Oil protester as she waited on the Mall hoping to catch a glimpse of the King.

The i newspaper quoted an anonymous senior police source saying that there had been "a very firm instruction not to damage the reputation of the UK", although the Home Office said it did not recognise the claim.

On Wednesday, Metropolitan Police Temporary Assistant Commissioner Matt Twist told MPs: "I felt under no pressure politically, I felt pressure to deliver a safe and secure operation, but that was because of the fact that it was a once-in-a-lifetime event for so many people and there would be hundreds of thousands of people in London to celebrate it, and also and importantly, this was the biggest protection operation we have ever run.

"There were 312 protected people that we managed to get in and out of the Abbey and across the footprint in about 90 minutes. So the stakes were enormously high, so I absolutely felt pressure to deliver a safe and secure operation. But that wasn't political pressure."

Mr Twist told the Commons Home Affairs Committee that officers had faced "the most challenging, fast moving and complex policing picture we've ever encountered for national celebration".

The six Republic members were the first people to be arrested under the sweeping Public Order Act, brought in days before the coronation.

They were held under suspicion of going equipped to "lock-on" - a measure protesters use to make it harder for police to move them - but later released without charge.

Metropolitan Police Commissioner Sir Mark Rowley has defended the force's actions in a letter to London Mayor Sadiq Khan, saying: "Had our officers not acted on reasonable grounds, based on the evidence in front of them in the moment and the potential risk to the event, there would now be much more serious questions to answer about the event."
