The Shrewsbury and Atcham MP recalled the exchange while speaking to Colin Murray during his show on BBC Radio 5 Live on Tuesday night.
Mr Kawczynski was a guest on a night when the first wave of ministers, led by Chancellor Rishi Sunak and Health Minister Sajid Javid, resigned from government.
In a lively debate, Mr Murry quoted Theo Clarke when she was stepping down as Trade Ambassador for Kenya, who cited the decision to promote Chris Pincher to Deputy Chief Whip as the main reason for her resignation.
Mr Pincher was suspended by the Conservatives last week after allegations he groped two men. The PM has since been forced to apologize for his handling of the dispute after it emerged he forgot to have been briefed on previous allegations of “inappropriate” behavior back in 2019.
Responding to a suggestion from the host that he was asking Ms Clarke to believe the Prime Minister’s claim that he had forgotten he had been told the allegations, Mr Kawczynski responded by referring to a trip to the electronics shop in Meole Brace, Shrewsbury, remembered.
He said: “When I was at Currys in Shrewsbury on Saturday buying a new vacuum cleaner, three employees in that building came up to me and said ‘You’ve got to help Boris, you’ve got to get Boris back’.
“I’ve never had people come up to me in an electronics store and ask me to support another prime minister I’ve met.”
“So if three had come up to you and said don’t support him and asked him to resign, would you have done that on the basis of three staffers in Currys?” the moderator replied. “I mean come on. You give me poppies.”
Mr Kawczynski defended himself, adding: “That actually happened, that’s not poppy. I tell the story.”
Asked if he was moving away from the subject of Mrs Clarke’s resignation, the Shrewsbury MP replied: “I’ll tell you a story that happened to me during my term in office on Saturday when I was not exercising my role as MP, but in Currys being in Shrewsbury to buy a new vacuum cleaner but people happened to recognize me as the local MP and they came up to me and said ‘please support Boris’. Well that is the truth.
“Why were you so amazed and angry that I described an incident that happened to me in my constituency?”
Mr Murray told him it was because he spoke about “three people who sold you a vacuum cleaner because of a specific question about the reasons an MP withdrew her support for the Prime Minister”.
“These are good, hard-working people working in my constituency, voters, and not a journalist or a radio commentator who’s obviously trying to paint a negative picture of the prime minister,” Kawczynski said.
After Mr Murray revealed that a YouGuv poll found 69 per cent of people believe Mr Johnson should step down, including 54 per cent of Tory voters polled, the Shropshire MP said the polls dropped Margaret Thatcher during her first term in office were often worse.
These included Montgomeryshire MP Craig Williams, who resigned as Parliamentary Private Secretary to the Chancellor.
In his letter, Mr Williams said he was “immensely proud” of the work done during Covid, the war in Europe and the pressure on the cost of living.
However, he said: “Following the recent vote of confidence, I had pledged my support to you, with one last reason for doubt. I thought it was right that we draw a line under past events and focus on restoring public confidence and focus on implementing good policies.
“It has been shown recently that this is becoming impossible.
“It is with deep regret that I resign from your government.”
