The chair of West Mercia police has said that Andrew Mitchell's position as the Conservative chief whip is untenable and the cabinet minister has no option but to resign.
Following a 40 minute meeting with the police confederation over the infamous 'pleb' comment, chairman Ken Mackaill said that they were no further forward but they appreciated the chance to meet Mitchell.
Despite the meeting, he said if the cabinet minister continued to challenge the accuracy of police records David Cameron should sack him.
Andrew Mitchell refused to tell the confederation what exactly was said outside to officers Downing Street according to Mackaill.
According to the police chief Mitchell remained tight lipped as "he did not want to impune officers integrity and start a 'firefight' with police."
However Mackaill admitted that is exactly what he has happened.
"Our concerns have not been addressed" he added.
Ken Mackaill said Mr Mitchell repeated a "profound apology, but that is balanced by his denial of specific and precise speech recorded by police at the time."
Andrew Mitchell avoided making comment as he left the meeting, his black Renault resolutely crawling away from the building, dogged by journalists.
Ian Edwards, the chair of the West Midlands Police Federation, had told The Huffington Post UK before the summit that officers were "very upset by him saying the officers' accounts aren't true".
When the incident was first reported Mitchell admitted to swearing at the officers who guard the prime minister's residence, but denied calling them "plebs".
However the official police account recorded Mitchell as saying: "Best you learn your f******* place... you don't run this f****** government... You're f****** plebs."
The class-based insult was toxic for the Tories, who have been trying to shake off their image as being led by out of touch "posh boys".
A YouGov poll published on Friday showed 50% of public think the row showed that Tory MPs see themselves as better than ordinary people.
The survey revealed that 60% of the public believe Mitchell's outburst "showed his true feelings" and 50% think his behaviour and attitudes reflect those of other Conservative MPs.
Desperate to hang onto his job, Mitchell dodged the Conservative Party conference in Birmingham so as not to be a distraction, but his cabinet colleagues who did make the journey were said to be openly discussing how to make him quit.
As a sign that his power to enforce discipline on backbenchers had vanished, one Tory MP said Mitchell now had "no authority at all" while the Daily Telegraph branded him a "laughing stock".Suggest a correction
