Balaclava-clad protesters pelt councillors with eggs while debating 'sanctuary for asylum seekers'

Toilets at the council offices in Sittingbourne were also "flooded" and lifts were "destroyed", Labour MP Kevin McKenna said.

Mr McKenna, MP for Sittingbourne and Sheppey, which includes Swale Borough, branded the incident an "attack on democracy itself" as he told the House of Commons of his horror at the "violent scenes".

"I’m horrified to report to you and to the House as a whole that last night in Swale Borough Council there were violent scenes as people wearing balaclavas in the public gallery itself violently intimidated councillors," he told MPs.

"They were threatening them, pelting them with eggs and missiles from the gallery.

"This is an attack on democracy itself. This is an attack on free speech.

"This is an attack on my constituents.

"The building was so badly vandalised afterwards, with toilets flooded, lifts destroyed.

"It can’t be used today and is not open.

"My constituents cannot access council services because of these actions.

"Our democracy is based on the ability to disagree with each other strongly, but never violently."

Commons speaker Sir Lindsay Hoyle branded it "an appalling situation", adding: "An attack on democracy is not acceptable."

Commons leader Sir Alan Campbell added: "There are plenty of examples, too many examples, of where MPs are intimidated, but it’s where other local representatives are intimidated too, and it’s simply not acceptable.

"So let me be very clear: those people, anyone involved in public life, should not be subject to harassment or intimidation for doing their job, and this House needs to stand united in sending out that message."

Kent Police confirmed there had been no arrests made "at this stage".

A force spokesman said: "Kent Police attended a reported disturbance during a public meeting at council offices in East Street, Sittingbourne, on the evening of Wednesday, December 10.

"Officers liaised with council officials at the premises at the end of the meeting and later received reports of criminal damage and a common assault.

"There have been no arrests at this stage and an investigation is underway into the circumstances."

Swale Borough Council was forced to close its offices following the incident.

"We’re currently working to get our office back open after they were damaged by some members of the public who attended a council meeting last night," a spokesman said.

"Toilets were vandalised, deliberate flooding caused water to pour through the ceiling in several areas, and a lift was also damaged.

"The police are examining the CCTV footage, and we will be supportive of any prosecutions they pursue."

Police have urged anyone with information to get in touch.
