UPS, meanwhile, were backing them “all the way”, Mr Bhimjiyani said.
A Metropolitan Police spokesperson confirmed officers had been called to the scene at 4.50pm on Saturday, July 12 and had spoken to both parties.
They added: “No persons made any formal complaints and no arrests were made. All parties were happy the matter was resolved at the location and no further police action was required.”
The West Hampstead councillor defected from Labour to the Conservatives in March, arguing that the party had moved away from his principles, such as support for “family values, small business, hard work, aspiration and cohesion”.
He was subsequently made Deputy Leader of the Conservative group and had been selected as the Tory candidate for Frognal at next year’s local elections.
On Thursday, the leader of Camden Tories, Councillor Steve Adams, told the LDRS he was “personally upset it had come to this” but that “action was in hand and the matter was being taken seriously”.
Shortly after, Hampstead and Highgate Conservatives told the LDRS they had suspended Mr Tiwari.
Party agent David Douglas MBE said: “In light of the serious allegations that have come to light, I want to clarify that neither I nor the Hampstead and Highgate Conservative Association had any prior knowledge of the reported matters. The moment we became aware, we acted promptly and collectively in unity as a team, in full accordance with the values and responsibilities expected of us.
“As of today, Cllr Tiwari no longer represents the Conservatives in his role on the council. We wish him well in addressing these matters and moving forward, but our priority remains upholding the integrity of our association and the principles we stand for,” Mr Douglas said.
Later that evening, Mr Tiwari’s office said he had resigned from the party and would not be standing for re-election next year. The LDRS was also told he regretted the verbal dispute with the shop and had apologised at the time.
The leader of Camden’s Labour administration, Councillor Richard Olszewski, had earlier called on his former colleague to resign. “Councillor Tiwari needs to explain what’s happening here, but on the face of this recording, this is appalling behaviour,” he said.
“Councillors have a code of conduct and there is an expectation of behaviour on us all, which I hope is being seriously reflected on by both him and his political group. Shop workers face enough abuse without it also coming from elected representatives.”
