The Times understands some party members are calling on him to resign his position as head of the party.
Robert Chris has lead the campaign to block plans for the new £108million theatre and civic office complex on the edge of Calverley Grounds, which is close to where he lives.
Dozens of Alliance supporters gathered outside the Town Hall earlier this month [October 8] to protest against the development.
A handful of people who supported the theatre plan were also outside.
A number of supporters of the Calverley Square theatre said they had banners ‘ripped out of their hands’ by anti-theatre protestors – including Robert Chris.
The party has confirmed the incident happened, with Alliance councillor Nicholas Pope admitting on social media: “There is clear footage that the TWA chairman snatched a banner and snapped it. It was childish behaviour that damaged someone else’s property. I do not condone this behaviour and spoke to the chairman immediately after I found out this had happened.”
Several Conservative councillors reported that on the night they were jeered and sworn at by Alliance supporters and protestors as they attempted to enter the Town Hall to debate the future of the theatre project.
Police became involved after two men made formal complaints following incidents outside the Town Hall. There is no suggestion those complaints relate to Robert Chris (pictured).
In a statement Kent Police said: “During the evening of Tuesday, October 8, 2019 a protest took place outside the Town Hall which was attended by a number of people. It is alleged two of the attendees were subjected to harassment, abusive language and threatening behaviour, by other protestors.”
They issued an image of a man they wanted to speak to in the belief he might have had have information that could ‘assist the investigation’.
The image was withdrawn earlier this week after a man handed himself into police.
A spokesman for Kent Police said: “A man attended Tonbridge Police Station on Monday at around 1pm. A 69-year-old man from Tunbridge Wells was dealt with by means of a community resolution order.”
